F5 Synthesis: The Time is Right

#SDN #Devops #Cloud #SDAS #SDDC The time is right for an answer to the layer 4-7 services question.

synthesis-logo"If you look at the standard SDN model, [Layer 4-7 services] are applications that can basically run on the [SDN] controller platform. But that's not the only way to do them. We'll hear about different approaches. Network services for SDN are going to be a big story in 2013." -- Brad Casemore, IDC

I love this quote from Brad (in fact this is the second time I've used it) because I've held the same opinion since SDN first burst onto the scene. At the time, the belief that layer 4-7 services were applications that could be deployed on the SDN controller seemed reasonable. Since that time, however, it's become accepted reality that an SDN controller built to manage and direct flows and packets - and the data path elements that carry out its commands - are not built to manage and direct streams and messages nor support a model that essentially forces it to participate in the data path.

But that's not to say that the SDN principles can't be applied to layer 4-7 services, or that SDN is the only way to improve service velocity and achieve the economy of scale necessary to enable every application to take advantage of application services to improve performance, security or reliability.

Remember that SDN (or something like it) was inevitable. Pressure mounting to increase service velocity and align with devops and app dev meant something had to change in the network. SDN appears to be that change for layer 2-3. And the time is right for a complementary change for layer 4-7 services.

We call it Synthesis™.

F5 Synthesis is an architectural vision for delivering device, network, and application services without constraints. The result is Software Defined Application Services™ (SDAS) delivered by a high-performance, all-active service fabric that when combined with new licensing models dramatically changes the economy of scale for application services. Applications previously unable to find room in their budget for pairs of dedicated hardware to enable services will be able to benefit from Synthesis' service-centric approach. Service velocity is improved by automation and orchestration at every layer, from fabric instances to the services provisioned for each application. 

F5 Synthesis comprises three core components:

  • High Performance Fabric – F5 physical and virtual products form an elastic, multi-tenant service fabric that delivers Software Defined Application Services. The service fabric can cluster up to 32 F5 devices deployed across any combination of hardware, software or cloud and supports up to 80* unique instances per device. The result is a combined throughput of 20 TB and connection capacity of 9.2 billion (that's more than 3 times the capacity needed to connect every Internet user in the world**). The service fabric is application-driven; its core services of availability, failover and clustering are focused on and driven by application requirements and needs. It is also highly programmable across configuration, control and data planes, with REStful APIs, data path scripting languages (iRules, node.js, Groovy) and event-based configuration scripting (iCall, TMSH) to ensure a highly responsive, extensible system.
  • Intelligent Services Orchestration – To realize the economy of scale necessary to enable a "leave no application behind" strategy, automated provisioning and orchestration is a must. F5’s architectural vision enables enterprises and service providers to seamlessly manage, scale, and automate the richest set of application services spanning device, network and application requirements for reliability, security and performance. Complementing the service fabric's multi-tenancy is a multi-tenant approach to management, enabling organizations to move closer to IT-as-a-Service without concern it might impact stability or security of the service fabric. 
  • Simplified Business Models – To better support the deployment of flexible services with cloud, hybrid, and usage-based IT models, F5 is simplifying its licensing and product bundling practices. Combined with a highly elastic service fabric and Intelligent Services Orchestration, simplified business models, F5 Synthesis enables organizations to achieve new economies of scale from both a cost savings and operational perspective.

 

In much broader terms, F5 Synthesis is the next evolution for application delivery. The changing application and network architecture landscape requires such an evolution. It is, after all, an application-driven world, and an application world needs solutions that better enable IT and business stakeholders to align technology to meet today's most pressing challenges: cloud enablement, security and mobility of devices, networks and applications.The application services that have become critical to ensuring the reliability, security and performance of a wide variety of applications must be provisioned, managed and scaled in a way that aligns with an application-driven world.

That way is F5 Synthesis and Software Defined Application Services.

CloudEXPO Stories
We are seeing a major migration of enterprises applications to the cloud. As cloud and business use of real time applications accelerate, legacy networks are no longer able to architecturally support cloud adoption and deliver the performance and security required by highly distributed enterprises. These outdated solutions have become more costly and complicated to implement, install, manage, and maintain.SD-WAN offers unlimited capabilities for accessing the benefits of the cloud and Internet. SD-WAN helps enterprises to take advantage of the exploding landscape of cloud applications and services, due to its unique capability to support all things cloud related.
In an era of historic innovation fueled by unprecedented access to data and technology, the low cost and risk of entering new markets has leveled the playing field for business. Today, any ambitious innovator can easily introduce a new application or product that can reinvent business models and transform the client experience. In their Day 2 Keynote at 19th Cloud Expo, Mercer Rowe, IBM Vice President of Strategic Alliances, and Raejeanne Skillern, Intel Vice President of Data Center Group and GM, discussed how clients in this new era of innovation can apply data, technology, plus human ingenuity to springboard to advance new business value and opportunities.
Business professionals no longer wonder if they'll migrate to the cloud; it's now a matter of when. The cloud environment has proved to be a major force in transitioning to an agile business model that enables quick decisions and fast implementation that solidify customer relationships. And when the cloud is combined with the power of cognitive computing, it drives innovation and transformation that achieves astounding competitive advantage.
DXWorldEXPO LLC announced today that "IoT Now" was named media sponsor of CloudEXPO | DXWorldEXPO 2018 New York, which will take place on November 11-13, 2018 in New York City, NY. IoT Now explores the evolving opportunities and challenges facing CSPs, and it passes on some lessons learned from those who have taken the first steps in next-gen IoT services.
The current age of digital transformation means that IT organizations must adapt their toolset to cover all digital experiences, beyond just the end users’. Today’s businesses can no longer focus solely on the digital interactions they manage with employees or customers; they must now contend with non-traditional factors. Whether it's the power of brand to make or break a company, the need to monitor across all locations 24/7, or the ability to proactively resolve issues, companies must adapt to the new world.
