Architecting Backup Infrastructure for Dynamic Workloads in the Cloud Recently I had to design the backup infrastructure for cloud workloads for a client in order to ensure that we comply with the Business Continuity and Disaster Recovery standards they have set. However, following traditional IT practices in the cloud quite often poses certain challenges. The scenario that we had to satisfy is best shown in the picture below: The picture is quite simple: Application servers have a backup agent installed The backup agent submits the data that needs to be backed up to the media server in the cloud The cloud media server submits the data to the backup infrastructure on premise, where the backups are stored on long-term storage according to the policy This is a very standard architecture for many of the current backup tools and technologies. Some of the specifics in the... (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...

There Is More to PaaS Than You Think

As described in the last week's post NIST defines three different cloud computing service models - IaaS, PaaS and SaaS. IaaS and SaaS are really easy to grasp but I see people struggling to understand the PaaS model. As a long-time application developer though I find the PaaS model the most compelling one for new applications. Here is why. I will look at two examples: one enterprise and one from the consumer world. Let's start with the enterprise scenario. If you examine any enterprise application portfolio you will find out that almost every development team has implemented it'... (more)

Open Source in the Cloud - How Much Should You Care?

In his opening keynote for Red Hat Summit, Jim Whitehurst, the CEO of Red Hat asked the audience: "Name an innovation that isn't happening in Open Source - other than Azure!" I can certainly add iPhone and AWS to the mix but let me stick to the cloud topic with the following question: "How much Open Source matters in the cloud?" Let's first elaborate on a two misconceptions about Open Source. Open Source Is Free Not really! In the cloud doesn't matter whether you are running on an Open Source platform or not - it is NOT free because you pay for the service. And for long Open Sou... (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...
