For a while already we have been working with a large enterprise client, helping them to migrate their on-premise workloads to the cloud. Of course, as added value to the process, they are also migrating their legacy development processes to the modern, better, agile DevOps approach. And of course, they have built a modern Continuous Integration/Continuous Delivery (CI/CD) pipeline consisting of Bitbucket, Jenkins, Artifactory, Puppet and some relevant testing frameworks. “It is all great!”, you would say “what is the problem?”. Because I am on all kinds of mailing lists for this client, I noticed recently that my dedicated email inbox started getting more and more emails related to the CI/CD pipeline. Things like unexpected Jenkins build failures, artifacts cannot be downloaded, server outages and so on and so on. You already guessed it – emails that report proble... (more)

AWS Outage and High Availability | @DevOpsSummit #SDN #AWS #Monitoring

After yet another cloud outage yesterday (see AWS’s S3 outage was so bad Amazon couldn’t get into its own dashboard to warn the world) the world (or at least its North American part) once again went crazy how dangerous the cloud is and how you should go build your own data center because you know better what is good for your business. Putting aside all the hype as well as some quite senseless social media posts about AWS SLAs, here is our thought process for developing highly available cloud services or more importantly making conscious decisions what our services’ SLAs should b...

Cloud Computing Service Models

In this post I will look at the three different service models for cloud computing as defined by NIST. More specifically I will look at the management and operations overhead for each one of the models and compare it to the traditional on-premise model. Traditional Model Let's look at how things have been done in the past. Traditionally enterprises have been responsible for managing their own IT infrastructure as well as the software stack that runs their applications. For small companies that meant hiring polyglot employees with wide range of skills varying from low level netw... (more)

Is Your Cloud Ready for the Enterprise?

Reading my newsfeed this morning I noticed several articles talking about the cloud and the enterprise. There is no doubt that the area is heating up with more and more acquisitions (IBM buys Softlayer), investments (GE invests $105M in Pivotal) and fights over big deals (IBM vs. AWS for the CIA cloud) but the question that comes up is: "Are the cloud platforms ready for the enterprise?" Being involved with numerous cloud projects I see five areas that enterprises emphasize when they evaluate their options. Those are not too different from the criteria they use for any other sof...

Why Shutting Down TechNet Is Not a Problem for IT Pros

While reading the news yesterday I stumbled upon the following article in Puget Sound Business Journal - Why is Microsoft alienating its biggest customers? IT pros want TechNet back. Everybody has the right to complain and sign a petition but more important is to understand the message Microsoft sends. Some think of it as "Microsoft doesn't care about IT Pros anymore", and they may be right; but the message sounds to me more like "Hey, IT Pros - the world is changing!" Although I think Microsoft could be a little bit more responsive to the complaints, I don't think IT Pros should... (more)
