Citrix, Microsoft and other stuff


AppEnsure – Independent Solution Review

logo Monitoring is always one of the most important topics that you have to define during implementation and management of Citrix environment. Usually it is decided to use standard monitoring tool used in your company – if that is good for enterprise then why it wouldn’t work for your Citrix platform? So you set required alerts, monitoring rules and wait…Wait for the first call from end user stating that his Citrix is not working at all, that she or he cannot do daily work. And you start your work – you try to find what might be the problem. You check your Citrix XenApp or XenDesktop servers and you have no idea what might be causing problem for your end user. You check the performance charts and alerts in the enterprise monitoring tool you decided to use and you see nothing. What is more you might only have insight into “your” servers which for sure doesn’t ease finding the root cause of the problem. And whenever you ask colleague from e.g. Exchange or SAP team they state that everything is working fine on their end and that it has to be Citrix that is breaking everything.

Everyone loves acronyms and the same apply to IT guys and cloud computing.

There are three main acronyms that are used in cloud computing area: Continue reading


CloudBusters – new blog series!!!

SaaS, PaaS, IaaS, DaaS and so on and so on… Those acronyms seems to be the most catchy words in the IT recently. Everywhere, everyone is talking about cloud, or I should rather say “THE  CLOUD”. And of course they are not talking about the weather forecast 🙂 Cloud topic seems to be now everywhere. In each company CIOs, CFOs, CEOs on the sound of the word “cloud” see saved money, better performance and of course higher profit of the company as they do not need to spend so much money on the infrastructure, people, trainings etc… Cloud is cheap, widely available and of course reliable. Every respecting IT company offers in its portfolio cloud solutions as the latest high-level service. But is that all really true or is it just a next way to get money from our wallets?

Inspired by a popular TV show MythBusters and also quite well known film GhostBusters I decided to start new blog series: The CloudBusters 😀 I hope that you will like it and really hope that you will provide some “cloud myths” you would like to bust with my help! I really encourage you to share your ideas. Let’s check if the “cloudization” is really the next step in IT services evolution.

And the best I left for the end of course. As every respecting [Thing]Buster I decided also to have my own arms. I hope you like it 😀
