F5 Synthesis: Fast, Fluent and Flexible

#sdas #sddc #sdn #devops #mobile F5 Synthesis 1.5 brings more performance, greater application fluency and increased flexibility for both application and mobile network providers.


Are you ready for millions of mobile visitors? With 20% of web traffic in the US and Canada coming from smartphones and tablets (Chitika) it's time to turn some cycles toward this growing segment and focus on more than just the BYOD.

Mobile visitors are just as easily frustrated by poorly performing applications as their traditional laptop and desktop visiting counterparts (and, in fact, they probably are the same consumers transitioning to more modern devices). The growth in device propagation also means its a growth market for attackers. And even if malware and viruses aren't running rampant on mobile device platforms that doesn't mean that applications and services can't leak data to mobile devices or that they can't participate in DDoS attacks. And phishing attacks work just as well in browsers on mobile devices as they do in browsers on the desktop.

Interestingly enough, while mobile platforms introduce some new challenges to ensuring security and performance of applications and data, many of the challenges and threats remain the same because they're really about data and applications and networks, not the end user device.

Addressing these challenges is made more difficult by the limited domains over which application providers have control. Consider that of the four most likely culprits of poor performance and security breaches, only one and a half are under the complete control of the application provider.




If we add cloud into the mix, the areas of control become even smaller. Generally speaking, applications deployed in cloud environments are not deployed along with the critical application services they need to ensure expectations of performance and security by end users and the business alike.

Increasingly, consumers often blame mobile network operators for poor performance, so it's important to note that they only have one of the four domains under their control: the mobile network. While they can and do offer services to improve the performance and security of applications traversing their networks, these services are not often capitalized upon by end-users or application providers.



F5 Synthesis enables cloud and application providers as well as mobile network operators the architectural framework necessary to ensure the performance, reliability and security of applications. The latest release of Synthesis, v1.5 with a focus on the enterprise, adds performance and security-related capabilities and services along with greater flexibility in management and orchestration to ensure that no matter what domains are under your control, you can deploy the application services appropriate to your applications.

This release is about fast, fluent and flexible Software Defined Application Services.


  • We've added a variety of TCP optimizations that improve performance for all applications that have an even greater impact on mobile application delivery. WebP conversion reduces the size of images, a per-application dedicated cache that uses HTML5 Local Storage capabilities and support for MPTCP ensure both application providers and mobile network operators can take advantage of Synthesis' performance services.
  • More SSD-enabled appliances means the F5 Synthesis High Performance Service Fabric gains greater multi-tenancy and improves the performance of application services, which in turn benefits application performance,
  • Simplified DNS deployment and optimized DNS resolution ensure DNS is never a bottleneck. F5 Synthesis' High Performance Service Fabric can support up to 418M DNS resolutions per second. That means it can resolve addresses for the equivalent  of every site on the Internet in 2 seconds[1]. 


  • As important as content level visibility is application fluency: the ability to not only inspect, but understand the unique languages of applications. F5 Synthesis now speaks more languages than ever, including TDS/MS SQL, FIX, and BER/DER.
  • We've added support for AES-GCM and ECC ciphers for TLS version 1.2 as well as supporting the ciphers needed for Perfect Forward Secrecy.
  • Our new Secure Web Gateway service speaks the language of the web, filtering URLs and inspecting web content for malware, and can do so even when it's hidden within SSL connections.


  • New cloud connector capabilities enable services across data centers and clouds supported by VMware, AWS, and OpenStack technologies, ensuring the migration to cloud doesn't result in the loss of critical application services needed for security and performance.
  • Synthesis v1.5 makes available BIG-IQ Device, part of Synthesis' Intelligent Service Orchestration, that enables automated discovery, licensing, inventory and UCS backup and restore capabilities for the Synthesis High Performance Services Fabric.
  • Also announced is the availability of iControl REST, our control plane API in a modern, accessible model. iControl REST enables organizations and mobile network operators to integrate, automate, orchestrate and dynamically manage Synthesis High Performance Service Fabric from virtually any HTTP-capable scripting or programming language.
  • We've taken Synthesis' Simplified Business Models and expanded them to include new streamlined license management for virtual editions of our platforms. License pools enable VE provisioning and decommissioning on-demand to enable broader use of services for burst capacity, testing, proof of concepts, or new development.


Synthesis v1.5 has a plethora of new capabilities, services and enhancements that enable application providers and mobile network operators to take advantage of the economy of scale afforded by the combination of a High Performance Service Fabric and Intelligent Service Orchestration to ensure that no matter which parts of the data path between users and applications are under control, they can be optimized and secured.

With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
Container technology is shaping the future of DevOps and it’s also changing the way organizations think about application development. With the rise of mobile applications in the enterprise, businesses are abandoning year-long development cycles and embracing technologies that enable rapid development and continuous deployment of apps. In his session at DevOps Summit, Kurt Collins, Developer Evangelist at, examined how Docker has evolved into a highly effective tool for application delivery by allowing increasingly popular Mobile Backend-as-a-Service (mBaaS) platforms to quickly crea...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
Growth hacking is common for startups to make unheard-of progress in building their business. Career Hacks can help Geek Girls and those who support them (yes, that's you too, Dad!) to excel in this typically male-dominated world.
