The notion that PaaS exists solely "in the cloud" as a discrete environment of developer services is hampering the maturation of enterprise PaaS The three most common answers to "give me an example of PaaS" are: Force.com, Azure, Google. I didn't even need to do an unscientific Internet survey to nail that one down. These are certainly fine examples of PaaS, but they are not necessarily examples of enterprise PaaS solutions. While off-premise PaaS offerings do address many of the same challenges being faced by enterprise operations today, they do so in a way that makes integration and control - not to mention the measurement and monitoring required by developers - nearly impossible. “Our core competency is application development; we are not a technical operations or cloud operations team,” Fischer said. PaaS technology saving time, money, changing application devel... (more)

Things Your Proxy Can’t Do | @DevOpsSummit #DevOps #Microservices

Proxies are one of the more interesting (in my no-doubt biased opinion) “devices” in the network. They’re the basis for caching, load balancing, app security, and even app acceleration services. They’re also a bridge between dev and ops and the network, being commonplace to all three groups and environments in most data center architectures. But not all proxies are built on the same architectural principles, which means not all proxies are created equal. A large number of proxies are half-proxies while others are full-proxies, and the differences between them are what mean the d... (more)

SDN: Network Scalability’s Secret Sauce By @LMacVittie | @CloudExpo #SDN #Cloud

Scaling things seems like such a simple task, doesn’t it? Open a new checkout line. Call a new teller to the front. Hire another person. But under the covers in technology land, where networking standards rule the roost, it really isn’t as simple as just adding another “X”. Oh, we try to make it look that simple, but it’s not. Over the years we (as in the industry ‘we’) have come up with all sorts of interesting ways to scale systems and applications within the constraints that IP networking places upon us. One of those constraints is that physical (L2) and logical (L3) addresses... (more)

F5 and the Cloud

There’s apparently been a bit of confusion over what, exactly, F5 thinks of cloud computing as an organization based on a recent blog post. I thought I’ve been fairly clear on where F5 stands in terms of cloud computing but I may be suffering what’s known as the “curse of knowledge”, which means I am so deeply entrenched in F5’s view of cloud that I forget that other people don’t have the luxury of that knowledge. So I’d like to take this opportunity to clear up any misconceptions that may be floating around and just set the record straight concerning F5 and cloud computing. TH... (more)

And the Killer App for Private Cloud Computing Is

The premise that if you don’t have an infrastructure comprised solely of Infrastructure 2.0 components then you cannot realize an automated, on-demand data center is, in fact, wrong. While the capabilities of modern hardware that come with Infrastructure 2.0 such as a standards-based API able to be leveraged by automation systems certainly makes the task all the more simple, it is not the only way that components can be automated. In fact, “legacy” infrastructure has been automated for years using other mechanisms that can certainly be incorporated into the dynamic data center ... (more)
