And what it means to #devops One of the realities of application development is that there are a lot of factors that go into its underlying architecture. I came of age during the Epoch of Client-Server Architecture (also known as the 1990s and later the .com era) and we were taught, very firmly, that despite the implication of "client-server" that there were but two, distinct "tiers" comprising an application, there were actually three. The presentation layer, the GUI, resided on the client. All business logic resided on the server, and a third, data access tier completed the trifecta. This worked well because developers tailored each application to a specific business purpose. Thus, implementation of business logic occurred along with application logic. There was no real reason to separate it out. As applications grew in complexity and use, SOA came of age. SOA int... (more)

F5 Synthesis: Faster Security

#sdas #infosec #ssl #DDoS #webperf SSL, like all cryptographic-based systems (and much to our chagrin, many security solutions) consumes a lot of resources. The longer the key lengths, the most complicated the key exchange, the more resources must be allocated to accomplishing both the handshake that establishes a secure connection and the ensuing bulk encryption of data traversing the wire. While PFS (Perfect Forward Secrecy) is a good response to concerns on the privacy of web-based conversations, the need to generate a new ephemeral key on a per message basis is going to cost...

Doing VDI, Only Better

There are three core vendors and protocols supporting VDI today. Microsoft with RDP, Citrix with ICA, and VMware with PCoIP. For most organizations a single vendor approach has been necessary, primarily because the costs associated with the supporting network and application delivery network infrastructure required to deliver VDI with the appropriate levels of security while meeting performance expectations of users and the need to maintain high availability. It’s a tall order that’s getting taller with every mobile client introduced, especially when you toss in a liberal dose o... (more)

Dear Slashdot: You Get What You Pay For

Open Source SSL Accelerator solution not as cost effective or well-performing as you think o3 Magazine has a write up on building an SSL accelerator out of Open Source components. It's a compelling piece, to be sure, that was picked up by Slashdot and discussed extensively. If o3 had stuck to its original goal - building an SSL accelerator on the cheap - it might have had better luck making its arguments. But it wanted to compare an Open Source solution to a commercial solution. That makes sense, the author was trying to show value in Open Source and that you don't need to shel... (more)

Finding New Life For SOA in the Cloud

We’ve been having quite a few discussions with analysts over the past few months on the subject of “cloud”. The interesting thing about these discussions is the vast array of points of view from which those analysts are viewing “cloud”. Some are focused on the network aspects, others on pricing/differentiation, and some are even very focused on what “cloud” means to applications – and the organizations that will, allegedly, take advantage of the cloud as a means of application deployment. One such analyst is Daryl Plummer of Gartner. Daryl has always been very application focuse... (more)
