If you think of automated provisioning as a formal written language definition, it does have some value in illuminating issues with partial automation or portions of the overall data center that are not automated. The path to automation is not a straight one at most organizations. It takes time, it takes resources, and even though there is a definable ROI, the press of business needs wins every time there is a conflict – because meeting business needs is pretty much the purpose of IT. But taking the staggered approach has costs too, and it’s good on occasion to look at them. I’ve admittedly created this view, but it is a way to consider your automation efforts and how well they’re working with regard to the end goal. We cover bare metal provisioning, application provisioning, multi-system provisioning, and cluster provisioning here. There is a relationship between ... (more)

Continuous Provisioning | @DevOpsSummit #DevOps #Microservices

Now, with more hardware! September 21, 2015, Don MacVittie, Sr. Solutions Architect. The “continuous” trend is continuing (get it..?), and we’ll soon reach the peek of the hype cycle, with continuous everything. At the pinnacle of the hype cycle, do not be surprised to see DDOS attacks re-branded as “continuous penetration testing!” and a fee associated with receiving them. But as with all hype cycles, there is some bit in them – usually quite a few bits in them – that actually pass the smell test in a real-world environment. With virtualization, we didn’t see the end of server... (more)

v.10 - iSessions in the Cloud (or a remote data center, you choose)

Well, I’ve covered the basics of iSessions – a secure, optimized tunnel between two BIG-IPs – so now it’s time to talk about usefulness, both today and going forward. Since iSessions are an infrastructure issue, the following works for redundant data centers also, assuming they have BIG-IPs in them, it’s just that cloud is the buzzword du-jour, and there’s actually a teentsy bit more benefit to using them for the cloud. First off, I assume that your cloud vendor has BIG-IPs (that is a safe assumption as of today), but you’re living in the real world, check with them first, there... (more)

Control Your NAS like You Control Your SAN

I was pondering over the weekend the concept that a SAN is relatively easy to manage – at least on the surface – because it is, in essence, a network in and of itself. Separated from the IP network, you have a switch that connects various SAN arrays and when your arrays become over-burdened, you can just drop another one in and plug it into the switch. Easy. And since the switch is not generally from the same vendor as the storage array, you can plug in whatever array you find most appealing this week. Migrating data between arrays can be tricky, but these days there are solution... (more)
