Avoid Cloud Disasters, Embrace the SLA

Talk of IT disasters can spark equal amounts of fear of them happening to us, and gratitude that the big one hasn’t happened to us yet. Network World offers some tips on what not to do when migrating to the cloud to avoid disasters—or, at the very least, grumbling users. They recommend splitting apps into two groups: those that will be migrated and those that will be replaced. Counting up all the costs of a cloud migration is also a necessary task before moving apps. There can be hidden people costs involved in moving data to the cloud, even though moving that data will save money over the long run.

Here’s more on the data centers running the cloud. The question posed recently to Oracle’s co-CEO was, essentially, how Oracle plans to compete in the public cloud market. That led to the question of how many data centers is enough data centers to truly be a cloud player competitive with the likes of AWS, Azure and Google Cloud. One AWS cloud expert tries to answer it, delving into redundancy (2+1 may be better than N+1), failover, latency (the speed of light comes into this), last-mile and other network issues, and legal and compliance factors. It’s a good look at where this giant cloud market stands today and where provider growth might happen—or not.

On the networking front, EMA did research on how enterprises are using and managing their wide area networks (WANs). That research found that just a little more than half of respondents are actively monitoring the SLA compliance of their WAN provider. That’s obviously a gap in IT management that should be addressed, since the WAN is ever more important these days with the growth of remote offices and users. SLAs can be somewhat tedious to negotiate and then manage, but this is a critical piece of IT’s job today. Cloud has made many things easier, but monitoring SLA compliance is one of the tradeoffs. Fortunately, full cloud visibility is what we do here—AppNeta can help you monitor all those SLAs.

Other recent research on modern networking, from Nemertes, finds SD-WAN adoption growing. About 18% of respondents in their survey are deploying SD-WAN of some type. Their reasons for adopting are mainly that they’ll get a better WAN that’s also less expensive. Some of the positive outcomes from using SD-WAN is that they’re seeing way fewer WAN service outages and less time spent troubleshooting the WAN. With this SD-WAN adoption, respondents are also shifting the way they use MPLS, with many moving immediate capacity growth to cheaper connections. This is all good news, but we’re sorry to say that you’re probably still going to have to monitor SLA compliance with your SD-WAN vendor.

Till next week, read the fine print.
