what are the core components of cloud infrastructure

Protecting your company’s data is critical. Resource pooling enables scalability for cloud providers and users … Programmability of RAN can be done both within the framework of 3GPP and within the complementary specifications of O-RAN. Selecting the right hardware platform and the virtualization environment is an important first step. The cloud infrastructure capacity is dynamically allocated to meet applications’ needs. Cloud RAN industry practices: Ericsson is a leading contributor to the most important open forums, actively supporting efforts to establish industry practices in Cloud RAN. To do this with an IT-focused approach at scale is unproven and current business models do not cater for back-to-back support agreement with RAN component suppliers, indicating an area where Ericsson can contribute to the maturity of the industry over time. This will also open up the RAN environment to a broader ecosystem and allows developers to build applications completely independently from innovations in the RAN domain. CLOUD ARTICLES, CALIFORNIA – DO NOT SELL MY INFORMATION. Key point: cloud storage can scale up or down as needed. In our last tutorial, we discussed thebest Cloud Computing Tutorial.Here, we will explore Cloud Computing architecture with diagram and example. Cloud infrastructure components In a cloud computing architecture, cloud infrastructure refers to the back-end hardware elements found within most enterprise data centers, but on much greater scale. No noisy neighbors. In an upcoming blogpost, we will elaborate more about how we enable automation, management and orchestration to deliver 5G services across all industries. We are delighted to share our expertise and help our customers unveil a whole new world of possibilities with Cloud RAN. It includes computing power, networking, and storage, as well as an interface for users to access their virtualized resources. Cloud RAN refers to realizing RAN functions over a generic compute platform instead of a purpose-built hardware platform. Applications live in massively scalable data centers where computational resources are able to be dynamically provisioned and shared in order to achieve significant economies of scale. It supports the overall cloud deployment. Of course, that might cost you more, so you have to weigh the benefits. Also known as Amazon compute, AWS has mainly EC2 (Elastic cloud … In order to host services and applications in the cloud, you need cloud infrastructure. The cloud infrastructure supporting the applications is made transparent to users by a user-centric interface. The only users were inside the company and inside the firewall, as were the apps. The goal is to explain how these components can be used in specific scenarios, which are based on real-world customer examples and therefore contain real-world requirements and constraints.

By virtualizing storage, compute and networking components, you can build from whatever services are available and not heavily utilized. Copyright 2020 TechnologyAdvice All Rights Reserved. SUBSCRIBE TO OUR IT MANAGEMENT NEWSLETTER, SEE ALL These consist of front end platforms, back end platforms, cloud based delivery model and a network. Or you can deploy a network connection on a switch with low traffic. Hypervisor is a firmware or low-level program. 3) Deployment Software . TechnologyAdvice does not include all companies or all types of products available in the marketplace. Cloud infrastructure refers to the hardware and software components that support the delivery of a cloud-based service. The goal is to simplify the combination of the private cloud and pubic cloud, often known as a hybrid cloud. Cloud RAN will be introduced into live networks with multiple radio access technologies, running predominantly as physical functions, with no impact on the quality of experience for its users. Big data, cloud and IoT are all firmly established trends in the digital transformation sphere, and must form a core component of strategy for forward-looking organisations.But in order to maximise the potential of these technologies, companies must first ensure that the network infrastructure is capable of supporting them optimally. At the Ericsson Blog, we provide insight to make complex ideas on technology, innovation and business simple. – deploying non-RAN functions in the virtualized system to add new functionality and additional value. Moreover, we will learn important components of Cloud Computing architecture and some cloud-based delivery like Saas, PaaS, IaaS. Think of cloud infrastructure as the tools needed to build a cloud. This unlocks new innovation value, enhancing the CSPs role and creates opportunities for monetization. Network technology has created a major change the relationship between cloud infrastructure and traditional IT. The Radio System consists of hardware and software for radio, baseband, power, enclosure, antenna and site solutions, the industry-leading MINI-LINK portfolio for microwave transmission and a fully integrated IP Router portfolio, all managed by a common management system. Bare metal solutions mean you bring everything, from the OS stack on up. The NFVI runs telecom, OSS, BSS, media and many types of IT and IoT applications. Everything was behind a firewall and facing inward. It acts as a Virtual Machine Manager. Cloud infrastructure is the bricks and mortar, IaaS is the store. Core Azure architectural components include Azure regions, Azure Availability Zones, resource groups, and the Azure Resource Manager. In this journey, Cloud RAN will adopt leading practices and become a foundation for openness and enable innovation in 5G. To realize this in scale requires leveraging cloud technologies and web-scale paradigms which leads us to Cloud RAN. If anything goes down, your work comes to a halt. It allows to share the single physical instance of cloud resources between several tenants. Ericsson pre-verified solutions: Ericsson can deliver a pre-verified Cloud RAN solution ranging from cloud infrastructure, RAN software, COTS hardware and accelerators and Radio gateways for optimized transport performance. It starts with control plane and user plane in the Centralized Unit and continues with latency sensitive radio processing functions in the Distributed Unit. No OS, either. Building the infrastructure to support cloud computing now accounts for more than a third of all IT spending worldwide, according to research from … Components of cloud infrastructure (Regions, Availability Zones, Data Centers, Virtualization, VMs, Bare Metal, Networking, and types of cloud storage (Direct Attached / Ephemeral, Persistant - File Storage, Block Storage, Object Storage, etc.) That 28-core Xeon is all yours. These systems will now have to manage physical network functions (PNF), virtual network functions (VNF), cloud native network functions (CNF) and end-to-end life cycle management of services across Cloud RAN, transport, 5G Core and underlying cloud infrastructure. Cloud RAN compatibility: Ericsson brings a leading radio portfolio meeting the unique needs of widely different networks and bring features that ensure Cloud RAN interworks seamlessly with installed base. To help with this process, companies use technologies such as hyperconverged infrastructure (HCI), where a vendor provides everything needed to install a turnkey cloud environment. Connected devices like a laptop, phone or server transfer data in and out of this larger cloud system. Check out Intellipaat’s AWS training and certification. SD-WAN is made for the public Internet and lets you use a VPN to encrypt traffic. If you have an application that is sensitive to issues of latency, you might have a costly problem. Open RAN is an industry term for open radio access network architecture with open interoperable interfaces and hardware-software disaggregation, which enable big data and AI-driven innovations in the RAN domain. It is also called the Virtual Machine Monitor (VMM), which creates & runs the virtual machine. Do you think when you log onto Gmail you are logging into the same physical server every time? A key learning from the virtualization journey of the core is that pre-verified solutions work best and are the most efficient, and that customer unique cloud environments come with additional work, cost and TTM overloads. This course covers the knowledge and skills to plan and implement a highly available, secure infrastructure with focus on Active Directory® Federation Service (AD FS), public key infrastructure (PKI), and Active Directory Rights Management Services (AD RMS). The O-RAN architecture includes two flavors of RAN Intelligent Controller to aid programmability of RAN: Ericsson sees that the Non-RT RIC is offering the greatest benefit. You might be connecting to a data center on the other side of the country. The result could be an app that impacts your performance, be it compute, in memory or the network. SD-WAN offers end-to-end encryption across the entire network, including the Internet, and all devices and endpoints are completely authenticated, thanks to software-defined security. Components of cloud infrastructure. AWS components. 5G calls for new levels of flexibility in architecting, scaling and deploying telecom networks. The cloud – and to some extent mobile – forces a break in that circle. Bare metal solutions mean you bring everything, from the OS stack on up. These include multisocket, multicore servers, persistent storage and local area network equipment, such as switches and routers. Process-as-a-Service. See what’s inside the Microsoft Cloud Infrastructure With the rapid proliferation of the Microsoft Cloud – which includes the popular Azure infrastructure and Microsoft 365 (formerly Office 365) suite of applications and services,– most organizations are operating in some kind of “hybrid” cloud/on-prem environment, and many others have moved completely to the Cloud. Cloud infrastructure is the layer of software and hardware between your internal systems and the public cloud. Cloud infrastructure in the public cloud is not a flawless solution. The current standard in WAN communication technology, Multiprotocol Label Switching (MPLS), is designed for use internally in your data center. This layer of cloud infrastructure has grown as public cloud has changed the structure of the data center and its hardware. It will add more versatility to network buildouts to address a variety of 5G use cases. to provide policy guidance to RAN on radio resource allocation and the 1 second control loop is short enough to capture almost all possible use-cases. Cloud storage also uses a distributed file system designed for different kinds of storage scenarios, such as object, big data, or block. Public cloud performance is not consistent, except perhaps at night when usage plummets. The disaggregation of hardware and software means that the RAN solution no longer has a unified node concept, instead consisting of software functions, NFVI and hardware versions, all with their own life cycles and release cadence. You can consider it the Best Practice framework of your Cloud Infrastructure. This applies to services as well as apps. But PaaS is expanded to offer more services, such as a complete development environment, including a Web server, tools, programming language, and database. A stepwise offering that will serve as a complementary addition to a Service Provider’s purpose-built 5G network.​. Switch on 5G with Ericsson Radio System. The bare metal solution is designed for specific environments where performance is critical, or if you want access to … IaaS is the foundation on which cloud infrastructure is built. Businesses need to create a secure data flow in their firewall to connect securely to the public cloud and keep intruders out, while at the same time maintaining acceptable levels of performance. COTS hardware including accelerators In bare metal you can, so you can do custom networking, like packet inspection. Cloud technology provides interesting possibilities to complement the existing tried and trusted technologies in the RAN domain. There are various components of AWS but we are elucidating on only key components. You can request a data center that is physically closer to you, to reduce the lag. From a technology maturity perspective, Cloud RAN will benefit greatly from clear industry practices and O-RAN innovation with a high degree of alignment towards 3GPP architecture. You can connect directly to the cloud provider, AWS as AWS Direct Connect, for example. Management, orchestration and automation - bringing end-to-end life cycle management of services across Cloud RAN, transport, 5G core and underlying cloud infrastructure. Service management is a measured package of applications and services that end users can easily deploy and manage via a public and/or private cloud vendor. From Wikipedia, the free encyclopedia Cloud computing architecture refers to the components and subcomponents required for cloud computing. Such software modularity and decomposition allow for: As the industry is transforming and introducing 5G networks, the management, orchestration and automation has become a cornerstone of 5G networks. Advertiser Disclosure: Some of the products that appear on this site are from companies from which TechnologyAdvice receives compensation. Note, these are issues unique to the public cloud and should not impact any private cloud infrastructure you deploy internally. To build and integrate such a system requires telecom expertise, the ability and experience to deliver pre-verified solutions and solid network evolution capabilities and skills. Azure is a cloud computing platform and infrastructure for building, deploying, and managing applications and services through a network of datacenters. In a cloud infrastructure, because everything is virtualized, nothing is tied to a particular physical server. In this video, Mike Chapple explains the cloud physical environment, network and communications, compute, virtualization, storage, and the management plane. When you are running a virtual instance, your VM is running on an AWS/Azure/IBM/Google server in a data center. Commercial-off-the-shelf server hardware with processors, Network Interface Cards (NICs) and hardware accelerators is the foundation. IaaS makes it possible to rent those cloud infrastructure components – compute, storage and networking – over the Internet from a public cloud provider. The next step up from IaaS is platform as a service (PaaS), which is built on the same IaaS platforms and hardware. Given the benefits of being able to bring multidomain knowledge at higher layers, Ericsson is currently focusing its R&D efforts on the Non-RT RIC, as opposed to the Near-RT RIC which overlaps considerably with RAN functionality already provided in feature rich RAN offerings as offered by Ericsson. Roadblocks On the Way to Digital Transformation, AWS vs. Azure vs. Google: 2020 Cloud Comparison. Network is the key component of cloud infrastructure. Cloud RAN (Radio Access Network) by Ericsson is a cloud-native software solution handling compute functionality in the RAN. With cloud infrastructure, DevOps teams can build their apps so they can deploy an app programmatically. The other issue is latency. Cobalt Iron’s enterprise-grade backup and recovery solution is known for its hands-free automation and reliability, at a lower cost. The good news is that cloud is made of the same fabric of servers, disks and networks that makes up traditional infrastructure. In this article, we’ll discuss the basics about each component and the functionality it provides. The bare metal solution is designed for specific environments where performance is critical, or if you want access to custom chips. Cloud backup that just works. The same applies to your AWS instances and your internal services, should you deploy a cloud infrastructure model for your internal infrastructure. You can’t do that in a traditional IT environment. They can tell an app to look for a low utilization server or to deploy as close to the data store as possible. This demands strong knowledge not only of Cloud RAN but of the entire existing telecom stack. Modern Slavery Statement | Privacy | Legal | © Telefonaktiebolaget LM Ericsson 1994-2020. Secure a smooth, fast and agile introduction of 5G, to reduce cost per gigabyte for your mobile broadband business and enabling industry digitalization for growth. Cloud Computing Architecture refers to the components and sub-components required for cloud computing. Cloud infrastructure is the foundation upon which sits platform and any application. – Bring RAN programmability to the network and start to capitalize on this foundation for innovation. For example, you can launch an application on a virtual server on hardware with low utilization. This compensation may impact how and where products appear on this site including, for example, the order in which they appear. With the introduction of Cloud RAN, edge compute, container-based architectures, and network slicing, the management and orchestration systems have become critical for success. Please sign up for email updates on your favorite topics. No OS, either. Your storage is on a specific storage array. The hypervisor can be defined as the firmware (a permanent set of instruction or code programmed into the read-only memory & is a low-level program) that acts as a virtual machine manager. Microsoft Azure relies on a few key architectural components to provide redundancy and high availability. RAN programmability is essentially the capacity to tailor the behavior and performance of the RAN through applications with access to multi-domain information. Cloud infrastructure components. The main list of components usually includes: servers, which are hardware or cloud resources (IaaS) for building computational resources, one of the core components of the infrastructure. Yet that is an even pricier solution since you are now using the provider’s own network. Cloud infrastructure consists of servers, storage devices, network, cloud management software, deployment software, and platform virtualization. Hypervisor is a firmware or low-level program that acts as a Virtual Machine Manager. Cloud technology offers new innovative alternatives for such Radio Access Network (RAN) deployments complementing existing proven purpose-built solutions. The solution to this is what’s called bare metal cloud. There can be issues, and typically these issues are serious. 2) Management Software. Cloud RAN refers to realizing RAN functions over a generic compute platform instead of a purpose-built hardware platform and managing the RAN application virtualization using cloud-native principles. Now businesses need to face outward, to AWS, Azure, Google Cloud, or other cloud companies. Microsoft manages these datacenters. Cloudification of RAN begins with running selected 5G RAN network functions in containers through Commercial off-the-shelf (COTS) hardware platforms. – operating in the control loop of 100s of milliseconds. Cloud RAN processing: We bring deep understanding of the demanding processing requirements in 5G RAN and active adoption of cloud technologies for application in the RAN domain. These private clouds don't have the compute capacity of an Amazon or IBM, but they do have the flexibility to spin up virtual instances and keep them in-house. Global RAN expertise: Ericsson brings significant RAN expertise and experience from delivering leading and robust networks throughout the globe. Like what you’re reading? The infrastructure resources consist of compute, network and storage. It is also possible to deliver network as a utility over the Internet, i.e., the consumer can customize the network route and protocol. One great example is the unique Ericsson Spectrum Sharing solution. Building a disaggregated system, that actually works as a cohesive entity is complex. In a traditional IT infrastructure, everything is tied to a server. As such, everything is virtualized, so the cloud-based infrastructure can be set up easily, duplicated, replaced, and shut down. Ericsson’s Network Serviced bring data-driven & AI-powered automations, digitalization processes, co-creation and deep competence knowledge to the deployment and operation of hybrid networks. Cloud storage with automated backup is scalable, flexible and provides peace of mind. Major cloud providers like Google cloud provide these services on multi-tenant servers. Up until now, IT equipment and data center systems adopted the circled wagon approach. If you allocate four cores on a 28-core Xeon, the other 24 are going to be rented out to someone else, and you have no way of knowing their identity. Cloud native architecture facilitates RAN functions to be realized as microservices in containers over bare metal servers, supported by technologies such as Kubernetes. Cloud infrastructure usually uses locally attached storage instead of shared disk arrays on a storage area network. However, simply forklifting existing 5G RAN software to a COTS platform is not enough. Cloud providers like AWS, Azure and Google charge more for SSD storage than they do for hard disk storage. The colocation data center hosts the infrastructure: building, cooling, bandwidth, security, etc., while the company provides and manages the components, including servers, storage, and firewalls. The AWS cloud follows a similar model in which companies can opt for cloud services instead of building large infrastructures, where they can get all the infrastructure they may need. Cloud infrastructure makes it possible for various applications, for example telco, operations supports systems, business support systems and IoT, to share infrastructure resources for their needs. AWS developed the 5 Pillars of Well-Architected Framework to help Cloud Architects build the most secure, fault-resilient, efficient, and high-performing IT infrastructure possible. Cloud infrastructure is a term used to describe the components needed for cloud computing, which includes hardware, abstracted resources, storage, and network resources. The model encompasses a huge capacity that can handle unpredictable changes … It uses intelligent routing to manage traffic to avoid bottlenecks, and most of the SD-WAN vendors have built their own private networks to supplement the public Internet, so you don’t have to compete with Netflix traffic. Cloud computing infrastructure is the collection of hardware and software elements needed to enable cloud computing. Components of Cloud infrastructure 1) Hypervisor. So, let’s start Cloud Computing Architecture. Specific server configurations are based on workload demands, especially for Distributed Units (DU) with its higher processing demands and stricter requirements on latency. The first problem is the issue of the noisy neighbor. All these combined make up cloud computing infrastructure. Because it is built for the public Internet, one of the biggest advantages to SD-WAN is security. Ericsson is a partner for your entire Cloud RAN journey, from design, solution creation, implementation and operations. Building a secure cloud infrastructure requires knowledge of core infrastructure components. Cost … It allows to connect cloud services over the Internet. It typically provides access to networking features, computers (virtual or on dedicated hardware), and data storage space. IaaS gives you the highest level of flexibility and management control over your IT resources. Hypervisor. Evolution to Cloud RAN is a multi-year journey. The VMware Cloud Infrastructure Architecture Case Study Series was developed to provide an understanding of the various components of the CIS. Cloud infrastructure consists of servers, storage devices, network connection, cloud management and deployment software, and platform virtualization. Disaggregating RAN software and hardware in Cloud RAN has the potential of independent innovation on software and hardware. Cloud infrastructure is the layer of software and hardware between your internal systems and the public cloud. Amazon cluster. The components of cloud infrastructure are typically broken down into three main categories: compute, networking, and storage: ... That 28-core Xeon is all yours. These are things like persistent storage, LAN equipment, and multi-core servers. RAN programmability – deploying non-RAN functions in the virtualized system to add new functionality and additional value. From our experience and domain expertise, we see a five-step journey towards Cloud RAN. Ericsson actively contributes to several of these alliances in order to enable innovation at global scale for the benefit of the whole industry. Additionally, Radio Access Networks have rather specific processing needs and requirements compared to typical IT applications or even core network workloads. In coming blogposts, we will discuss in more detail different types of processing architectures including how to best realize an efficient hardware architecture for Cloud RAN. In a bare metal environment, the CPU is not virtualized. It differentiates from traditional on-premise data centers in terms of its system architecture and service delivery model: A typical cloud infrastructure is located off-premise and accessed via the internet. To assess AWS cloud computing capabilities, we must first examine the basic components of the cloud. One solution is to change the location of your app. These components typically consist of a front end platform (fat client, thin client, mobile),back end platforms (servers, storage), a cloud based delivery, and a network (Internet, Intranet, Intercloud). For example, in a virtualized environment, you cannot access the networking chip. This allows businesses to turn their traditional on-premises data center into cloud-like infrastructure that can managed from a single dashboard. Management Software. Are you interested in learning AWS from expert? 5G calls for new levels of flexibility in architecting, scaling and deploying telecom networks. It doesn’t handle high bandwidth apps very well and is easily overloaded. Infrastructure as a Service (IaaS) IaaS contains the basic building blocks for cloud IT. Under this context, Cloud RAN management is not just about managing hybrid network functions in RAN, but also about bringing cloud native principles, programable networks and model driven management and orchestration systems. Scalability and rapid elasticity. How important is the cloud? The virtual resources mirror a physical infrastructure, with components like servers, network switches, memory and storage clusters. A cloud infrastructure virtualizes all components of a data center. With its placement higher up in the architecture, it can access a larger pool of RAN data as well as external data sources such as weather, traffic, first responder events etc. The Ericsson approach to Cloud RAN is  built to be cloud agnostic but to extract maximum value, CSPs should consider a balanced approach to disaggregation. Ericsson has broken down Cloud RAN into four components that create the foundation for a successful Cloud RAN implementation. A common practice among cloud users is to spin up a bunch of virtual machines, run benchmarks to see which perform best, and shut down the ones they don’t need. To assess the cloud computing capabilities of AWS we have to first look into the core components of the cloud. The components of cloud infrastructure are typically broken down into three main categories: compute, networking, and storage: Storage is where cloud infrastructure parts ways from the traditional data center infrastructure. Cloud infrastructure is the back-end components and other elements that are found within most data centers. The type of storage used depends on the tasks you need handled. This requires the use of accelerators to manage Layer 1 pipeline functions and is especially critical to meet the demands of Massive MIMO radios. All services are delivered through the Infrastructure as a Service (IaaS) model. Application-as-a-Service: Application-as-a-Service (also known as SAAS) is … No noisy neighbors. Apps run on dedicated physical servers. That physical server is likely a two-socket rack mount with two Intel Xeons and a lot of memory. Incorporating many different tools and solutions, this infrastructure is the essential system for a successful cloud computing deployment. It enables to share a physical instance of cloud resources between several customers. Management software assists to maintain and configure the infrastructure. No, it’s a virtualized server at any one of dozens of Google data centers. NFVI is a telco cloud platform which virtual network functions (VNFs) and container-based applications are deployed on.
