(Belarus) Foundation for data centers: Juniper MetaFabric architecture
Despite the obvious advantages of introducing modern data centers, there are a number of serious problems associated with the operation and implementation of new technologies and services. Juniper Networks offers a solution designed to overcome these challenges and increase the efficiency of data centers. About this under the cut.
With the advent of data centers based on virtualization technologies, enterprises and service providers have gained wide opportunities to use information infrastructure as sources of income. Cloud computing, mobility and big data are transforming the business, making it increasingly connected with IT. However, with expanding capabilities, data center infrastructure requirements are increasing in terms of flexibility, efficiency and cost-effectiveness. New applications and services require constant dynamic modification of the network. However, the complex and fixed network structure, difficulties in managing and troubleshooting, and weak communications with the rest of the infrastructure and other components often impede the necessary flexibility. As a result, the IT departments of organizations are faced with the need for major changes to the network each time a new protocol is introduced,
All this leads to two key problems in organizing a network of data centers. The first is that because of the high complexity, the network increases the payback period of investments and prevents the data center from working quickly, the second is in the low value of the network over time due to the need for constant changes. The MetaFabric architecture developed by Juniper Networks is called upon to help overcome these difficulties and allow the improvement of network infrastructure in accordance with the requirements.
The ideal data center: myths and facts
Manufacturers have repeatedly tried to solve the problems described above using simplified network architectures, automation tools, and the introduction of software-configured networks. However, many of these solutions are designed to work with the so-called ideal version of the data center, with which several common myths are associated.
The first is that the data center can only exist within the office. In fact, data centers are not limited to one physical location and in most organizations have a distributed structure.
The following myth claims that 100% of the data centers are already virtualized or will be virtualized in the near future. Data centers are a combination of virtual and physical elements. Although many companies use server virtualization technologies, even the most technically equipped remain with non-virtualized applications. This may be due to the existing application architecture or to the use of servers without operating systems and end devices with 86-bit operating systems that cannot be fully virtualized.
The essence of another myth lies in the assertion that workload mobility is a common and ubiquitous phenomenon. However, this issue is not so simple as it seems. Typically, mobility is limited to highly specialized maintenance windows for backing up applications and data. Managing such workloads is difficult, regardless of where they are located - in different countries or in the same building. Complexity is associated with the high performance and bandwidth required to move applications and the datasets they use closer to each other.
Last, fourth myth - security focuses on the application. In fact, security policies are geo-referenced, as well as hardware and software platforms, which increases the overall level of complexity. Therefore, organizations are often forced to combine different security products to perform various tasks in the data center.
In fact, the problem with such ideal environments is that applications are “locked up” in certain geographic locations, and the network and security system are made up of fragmented solutions. The exchange of information and the sharing of resources and data are difficult due to the above difficulties, security policies, the need to comply with regulatory requirements and performance problems.
Next Generation Data Center
To achieve the necessary infrastructure flexibility, such “ideal” data centers must be synchronized and networked to allow resource sharing. However, the creation of such a network is impossible without an appropriate platform. This is exactly what Juniper MetaFabric architecture is that allows you to create simple intelligent data centers, accelerating the return on investment and increasing network value and security.
MetaFabric takes a simplified approach to physical and virtual infrastructure, network operations and security, reducing operational costs and simplifying the deployment, operation, integration and scalability of the data center network and security systems. Based on open standards, it interacts with any application and eliminates the need for binding to the products of a particular vendor, specific protocols, orchestration platforms, security technologies, and controllers of software-configured networks. MetaFabric uses comprehensive network virtualization, analytics and automation to provide data that enables the deployment of proactive intelligent networks optimized for specific applications.
The MetaFabric architecture makes it easy to manage distributed data centers. Customers can choose their own controls, such as Juniper Networks Junos Space Network Director, software-controlled network controllers (including Juniper Networks Contrail and VMware NSX) and cloud orchestration platforms, such as OpenStack. All components of the architecture have the ability to share information, providing an integrated approach to analytics.
The platform uses standardized network protocols and extends these functions to a management layer that supports superimposed virtual networks and software-configured network protocols. Such integration provides a comfortable interaction between physical and virtual gateways.
Data center performance is greatly enhanced by streamlining traffic routes. MetaFabric uses universal switching factories with low predicted latency. Ethernet VPN (EVPN) allows you to automatically and dynamically change traffic routes, providing maximum efficiency in the use of network resources.
An important feature of the new architecture is the ability to securely modify the network. No matter what the task, be it updating the software, installing an additional rack, adding an adapter or even creating a new data center node, MetaFabric provides seamless implementation at any level, while maintaining open standardized technologies.
It is worth remembering that MetaFabric is not a separate product or technology. The architecture is a turnkey solution for creating a data center, developed on the basis of a combination of highly efficient switching, routing and security platforms using multifunctional microprocessors, programmable systems, adaptable software, orchestration, software-configurable networks and open APIs for integration with the existing technological ecosystem. MetaFabric introduces simple and open component components suitable for any data center deployment scenario.
The switches included with MetaFabric are optimized for data centers. They provide the optimal balance of performance, functionality, and flexibility needed to support any switching fabric for any application. High-performance gateways act as routers, allowing using standard protocols and open interfaces to combine several data centers into a single network.
The use of a flexible and fully open software-configurable network provides automation and orchestration of the process of creating virtual networks for new services, which, in turn, helps to achieve greater flexibility and increase revenue. Adaptive security systems using innovative protection technologies make it possible to effectively detect and respond to various threats quickly. And fast application delivery and high availability are ensured through the use of intelligent controls.
Juniper MetaFabric includes an entire ecosystem in which various technologies successfully interact and which is equipped with a full range of computing resources, data storage systems, virtualization tools, security functions, software-configured networks and orchestrations.
Thus, the new architecture provides customers with the basis for building a network infrastructure that is flexible enough for future development and provides long-term investment protection.
Who benefits from MetaFabric architecture
Juniper MetaFabric’s simple and open approach will help reduce the return on investment and achieve higher long-term value for both companies with one geographically located data center and enterprises with a distributed data center planning to develop through the introduction of cloud computing, mobile technologies and big data. This applies to any organization in any vertical industry or service provider segment, including:
• IT enterprises planning further virtualization;
• Financial institutions that require a higher degree of reliability and higher productivity;
• Government agencies where certain safety rules are required;
