Comparing costs between public cloud providers


I am often discussing the different platforms with people and we often end up discussing the different prices. People keep on asking me how much money you have to invest for a specific number of instances. It is necessary to look up different websites and so on. I came up with the idea of creating a simple cost comparison calculator with javascript on my blog. And I can now say: here it is! Click here to go to the Calculator. The cost comparision calculator gives you 3 different options: Calculate the best price for cpu intense applications Calculate the best price for memory intense applications Calculate the best cheapest instances available. The cost comparison calculator currently compares the following platforms: Amazon EC2 Google Compute Engine Rackspace Cloud Servers Windows Azure Virtual Machines A challenge is, what to compare. Each vendor has different instance types, so a comparison is often not so easy. Therefore, I have decided to split the comparison into different challenges as described

Cloud Computing for CIOs: Elements of IT Security for Cloud Computing


We often hear executives in various companies talk about IT security. Especially when it comes to Cloud Computing, security is a major topic. Many IT leaders and CIOs are afraid of Cloud Computing when it comes to security. To find out about security in the Cloud, we have to discuss what elements of IT security are necessary to Cloud Computing. The 6 elements of IT security are called “ACACIA”. Availability Availability says that all Elements within an IT landscape must be available. Users shouldn’t be limited by outages or similar things. If we talk about the Cloud, we need to handle this with failover systems, such as different availability zones. Integrity This means that the IT landscape is fully operational and there are no alien servers – which, for instance, could have been added by competitors or hackers. It could also happen that some malware is installed. Therefore, it is necessary to protect your Cloud-based infrastructure, as you would do

Cloud Computing for CIOs: Understanding the Innovation Level of a Technology


To manage Technology in a good manner, CIOs need to understand what type of Technology they deal with. This is also very important when it comes to Cloud Computing. We have different technology topics and levels with Cloud Computing such as Software as a Service, Platform as a Service and Infrastructure as a Service. But how mature and how advanced is a technology? To figure that out, we have 4 different technology types. Basic Technology The first technology type is called “basic technology”. This means that it is a technology that has been around for a while, is very mature. However, there is only very little to almost no innovation level involved. Technologies associated with Cloud Computing usually don’t fall in this type of technology since there is still a lot of innovation going on with Cloud Computing. However, we could call Virtualization a basic technology. Key Technology Next, there is the “key technology”. This technology type also refers to
