Inarguably one of the drivers of software-defined architectures (cloud, SDDC, and SDN) as well as movements like DevOps is the complexity inherent in today's data center networks. For years now we've added applications and services, and responded to new threats and requirements from the business with new boxes and new capabilities. All of them cobbled together using traditional networking principles that adhere to providing reliability and scale through redundancy.
The result is complex, hard to manage, and even more difficult to change at a moments notice.
Emerging architectural models based solely on cloud computing models or as part of larger, software-defined initiatives, attempt to resolve this issue by introducing abstraction and programmability. To get around the reality that deploying new services in a timely manner takes days if not weeks or even months, we figure that by moving to a programmatic, software-based model we can become more efficient.
Except we aren't becoming more efficient, we're just doing what we've always done. We're just doing it faster. We're not eliminating complexity, we're getting around it by adding a layer of scripts and integration designed to make us forget just how incredibly complex our networks really are.
One of the primary reasons our networks are the way they are is that we're reactive.
What we've been doing for years now is just reacting to events. Threats, new applications, new requirements - all these events inevitably wind up with IT deploying yet another "middle box." A self-contained appliance - hardware or software - that does X. Protects against X, improves Y, enhances Z. And then something else happens and we do it again. And again. And ... you get the point. We react and the result is an increasingly complex topological nightmare we call the data center network.
What we need to do is find a better model, a strategic model that enables us to deploy those solutions that protect against X, improve Y and enhance Z without adding complexity and increasing the already confusing topology in the network. We need to break out of our tactical mode and start thinking strategically so we can transform IT to be what it needs to be to align IT results with business expectations.
That means we need to start thinking platform, not product.
Platform is Strategic. Product is Tactical.
We know that the number of services actually in use in the data center has been increasing in response to all the technological shifts caused by trends like security, cloud and mobility. We’ve talked to customers that have more than 20 different services (and vendors) delivering services critical to the security, performance and reliability of applications. Every time a new threat or a new trend impacts the data center, we respond with a new service.
That’s one of the reasons you rarely see a detailed architectural diagram at the application flow level – because every single interaction with a customer, partner or employee can have its own unique flow and that flow traverses a variety of services depending on the user, device, network and application and even business purpose.
That's the product way.
What we need to do is shift our attention to platforms, and leverage them to reduce complexity while at the same time solving problems - and doing so faster and more efficiently. That's one of the primary benefits of Synthesis.
Synthesis' High Performance Services Fabric is built by gluing together a platform - the ADC - using new scalability models (ScaleN). The platform is what enables organizations to deploy a wide variety of services but gain operational efficiencies from the fact that the underlying platform is the same. F5 Software Defined Application Services (SDAS) are all deployable on the same, operationally consistent platform regardless of where it might physically reside. Cloud, virtual machine or hardware makes no difference. It's the platform that brings consistency to the table and enables rapid provisioning of new services that protect X, improve Y and enhance Z.
In the past year we've brought a number of new services to the Synthesis architecture including Cloud Identity Federation, Web Anti-Fraud, Mobile optimizations and a Secure Web Gateway. All these services were immediately deployable on the existing platform that comprises the Synthesis High Performance Services Fabric. As we add new capabilities and services, they, too, are deployable on the same platform, in the same fabric-based approach and immediately gain all the benefits that come from the platform: massive scalability, high performance, reliability and hardened security.
A platform approach means you can realize a level of peace of mind about the future and what might crop up next. Whether it's a new business requirement or a new threat, using a platform approach means no more shoehorning a new box into the topology. It means being able to take advantage of operational consistency across cloud and on-premise deployments. It means being able to expand capabilities without needing to expand budgets to support new training, new services, and new contracts.
A platform approach to service deployment in data center networks is strategic. And with the constant rate of change headed our way thanks to the Internet of Things and mobility, the one thing we can't afford to to go without is a sound strategy for dealing with the technological ramifications on the network.
There's a lot of things we do to improve the performance of web and mobile applications. We use caching. We use compression. We offload security (SSL and TLS) to a proxy with greater compute capacity. We apply image optimization and minification to content. We do all that because performance is king. Failure to perform can be, for many businesses, equivalent to an outage with increased abandonment rates and angry customers taking to the Internet to express their extreme displeasure.

Adding public cloud resources to an existing application can be a daunting process. The tools that you currently use to manage the software and hardware outside the cloud aren’t always the best tools to efficiently grow into the cloud. All of the major configuration management tools have cloud orchestration plugins that can be leveraged, but there are also cloud-native tools that can dramatically improve the efficiency of managing your application lifecycle. In his session at 18th Cloud Expo, ...

Let's just nip the conflation of these terms in the bud, shall we?
"MIcro" is big these days. Both microservices and microsegmentation are having and will continue to have an impact on data center architecture, but not necessarily for the same reasons. There's a growing trend in which folks - particularly those with a network background - conflate the two and use them to mean the same thing.
They are not.
One is about the application. The other, the network. T...

Before becoming a developer, I was in the high school band. I played several brass instruments - including French horn and cornet - as well as keyboards in the jazz stage band. A musician and a nerd, what can I say? I even dabbled in writing music for the band. Okay, mostly I wrote arrangements of pop music, so the band could keep the crowd entertained during Friday night football games. What struck me then was that, to write parts for all the instruments - brass, woodwind, percussion, even k...

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...

Sharding has become a popular means of achieving scalability in application architectures in which read/write data separation is not only possible, but desirable to achieve new heights of concurrency. The premise is that by splitting up read and write duties, it is possible to get better overall performance at the cost of a slight delay in consistency. That is, it takes a bit of time to replicate changes initiated by a "write" to the read-only master database. It's eventually consistent, and it'...
