Cloud storage also uses a distributed file system designed for different kinds of storage scenarios, such as object, big data, or block. 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. 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. 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. 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. Bare metal solutions mean you bring everything, from the OS stack on up. For example, you can launch an application on a virtual server on hardware with low utilization. In order to host services and applications in the cloud, you need cloud infrastructure. SD-WAN is made for the public Internet and lets you use a VPN to encrypt traffic. So, let’s start Cloud Computing Architecture. Switch on 5G with Ericsson Radio System. Cloud backup that just works. Everything was behind a firewall and facing inward. 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. From our experience and domain expertise, we see a five-step journey towards Cloud RAN. Microsoft manages these datacenters. 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. Cloudification of RAN begins with running selected 5G RAN network functions in containers through Commercial off-the-shelf (COTS) hardware platforms. The model encompasses a huge capacity that can handle unpredictable changes … Connected devices like a laptop, phone or server transfer data in and out of this larger cloud system. As the cloud has grown, many enterprises have adopted an internal cloud model, often known as a private cloud. If anything goes down, your work comes to a halt. The only users were inside the company and inside the firewall, as were the apps. The infrastructure resources consist of compute, network and storage. This requires the use of accelerators to manage Layer 1 pipeline functions and is especially critical to meet the demands of Massive MIMO radios. Cobalt Iron’s enterprise-grade backup and recovery solution is known for its hands-free automation and reliability, at a lower cost. 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. This unlocks new innovation value, enhancing the CSPs role and creates opportunities for monetization. It is also called the Virtual Machine Monitor (VMM), which creates & runs the virtual machine. We have a leading 5G position and rich knowledge of building and running several generations of robust and reliable radio access networks globally. – Bring RAN programmability to the network and start to capitalize on this foundation for innovation. 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. Additionally, Radio Access Networks have rather specific processing needs and requirements compared to typical IT applications or even core network workloads. 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. To assess the cloud computing capabilities of AWS we have to first look into the core components of the cloud. The first problem is the issue of the noisy neighbor. 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. 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.) Process-as-a-Service. 5G calls for new levels of flexibility in architecting, scaling and deploying telecom networks. Cloud providers like AWS, Azure and Google charge more for SSD storage than they do for hard disk storage. In a traditional IT infrastructure, everything is tied to a server. Cloud infrastructure is a term used to describe the components needed for cloud computing, which includes hardware, abstracted resources, storage, and network resources. 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. 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. Amazon cluster. Like what you’re reading? To really realize the value of Cloud RAN one needs to embrace cloud native architecture. No, it’s a virtualized server at any one of dozens of Google data centers. Cloud infrastructure is the foundation upon which sits platform and any application. There are various components of AWS but we are elucidating on only key components. These consist of front end platforms, back end platforms, cloud based delivery model and a network. No OS, either. It allows to connect cloud services over the Internet. There can be issues, and typically these issues are serious. Scalability and rapid elasticity. Think of cloud infrastructure as the tools needed to build a cloud. We are delighted to share our expertise and help our customers unveil a whole new world of possibilities with Cloud RAN. – deploying non-RAN functions in the virtualized system to add new functionality and additional value. Cloud RAN refers to realizing RAN functions over a generic compute platform instead of a purpose-built hardware platform. All these combined make up cloud computing infrastructure. This demands strong knowledge not only of Cloud RAN but of the entire existing telecom stack. To realize this in scale requires leveraging cloud technologies and web-scale paradigms which leads us to Cloud RAN. You might be connecting to a data center on the other side of the country. 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. As such, everything is virtualized, so the cloud-based infrastructure can be set up easily, duplicated, replaced, and shut down. Cloud Computing Architecture refers to the components and sub-components required for cloud computing. Cloud infrastructure refers to the hardware and software components that support the delivery of a cloud-based service. The good news is that cloud is made of the same fabric of servers, disks and networks that makes up traditional infrastructure. Cloud technology offers new innovative alternatives for such Radio Access Network (RAN) deployments complementing existing proven purpose-built solutions. The components of cloud infrastructure are typically broken down into three main categories: compute, networking, and storage: ... That 28-core Xeon is all yours. This allows businesses to turn their traditional on-premises data center into cloud-like infrastructure that can managed from a single dashboard. The solution to this is what’s called bare metal cloud. 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. Management, orchestration and automation - bringing end-to-end life cycle management of services across Cloud RAN, transport, 5G core and underlying cloud infrastructure. NFVI is a telco cloud platform which virtual network functions (VNFs) and container-based applications are deployed on. Ericsson is a partner for your entire Cloud RAN journey, from design, solution creation, implementation and operations. Network technology has created a major change the relationship between cloud infrastructure and traditional IT. It starts with control plane and user plane in the Centralized Unit and continues with latency sensitive radio processing functions in the Distributed Unit. They can tell an app to look for a low utilization server or to deploy as close to the data store as possible. It doesn’t handle high bandwidth apps very well and is easily overloaded. Cloud infrastructure is the layer of software and hardware between your internal systems and the public cloud. In a cloud infrastructure, because everything is virtualized, nothing is tied to a particular physical server. The current standard in WAN communication technology, Multiprotocol Label Switching (MPLS), is designed for use internally in your data center. 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. Now businesses need to face outward, to AWS, Azure, Google Cloud, or other cloud companies. The cloud – and to some extent mobile – forces a break in that circle. No noisy neighbors. The bare metal solution is designed for specific environments where performance is critical, or if you want access to … Cloud infrastructure components. The virtual resources mirror a physical infrastructure, with components like servers, network switches, memory and storage clusters. Hypervisor is a firmware or low-level program. Do you think when you log onto Gmail you are logging into the same physical server every time? And a simplified tool to outline and gauge services is vital for cloud administrators to market functionality. 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). Cloud native architecture facilitates RAN functions to be realized as microservices in containers over bare metal servers, supported by technologies such as Kubernetes. TechnologyAdvice does not include all companies or all types of products available in the marketplace. In an upcoming blogpost, we will elaborate more about how we enable automation, management and orchestration to deliver 5G services across all industries. Cloud technology provides interesting possibilities to complement the existing tried and trusted technologies in the RAN domain. Moreover, we will learn important components of Cloud Computing architecture and some cloud-based delivery like Saas, PaaS, IaaS. 2) Management Software. 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. The bare metal solution is designed for specific environments where performance is critical, or if you want access to custom chips. 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. That 28-core Xeon is all yours. 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. You can consider it the Best Practice framework of your Cloud Infrastructure. Ericsson has broken down Cloud RAN into four components that create the foundation for a successful Cloud RAN implementation. Cloud RAN (Radio Access Network) by Ericsson is a cloud-native software solution handling compute functionality in the RAN. But PaaS is expanded to offer more services, such as a complete development environment, including a Web server, tools, programming language, and database. You can’t do that in a traditional IT environment. Ericsson actively contributes to several of these alliances in order to enable innovation at global scale for the benefit of the whole industry. That physical server is likely a two-socket rack mount with two Intel Xeons and a lot of memory. For example, in a virtualized environment, you cannot access the networking chip. It allows to share the single physical instance of cloud resources between several tenants. 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. All services are delivered through the Infrastructure as a Service (IaaS) model. Redefine customer experience in real time, Independent life cycle management following DevOps principles and Continuous Integration and Continuous Delivery (CI/CD), Application-level reliability with platform abstraction, Simplified operations and maintenance with network automation. Evolution to Cloud RAN is a multi-year journey. Infrastructure as a Service (IaaS) IaaS contains the basic building blocks for cloud IT. This brings key values needed in 5G networks such as automation, flexibility, faster time to market, managing complex networks, and better customer experience. 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. IaaS gives you the highest level of flexibility and management control over your IT resources. Building the infrastructure to support cloud computing now accounts for more than a third of all IT spending worldwide, according to research from … 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. Application-as-a-Service: Application-as-a-Service (also known as SAAS) is … The result could be an app that impacts your performance, be it compute, in memory or the network. If you have an application that is sensitive to issues of latency, you might have a costly problem. 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. These include multisocket, multicore servers, persistent storage and local area network equipment, such as switches and routers. Resource pooling enables scalability for cloud providers and users … 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. Also known as Amazon compute, AWS has mainly EC2 (Elastic cloud … Of course, that might cost you more, so you have to weigh the benefits. It acts as a Virtual Machine Manager. Your storage is on a specific storage array. 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. Building a disaggregated system, that actually works as a cohesive entity is complex. 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.
