I saw this happening with other movements before, sooner or later I knew it would happen to DevOps. Culture is so fragile. Culture is fragile because it rely on people vision. It's so easy to understand something wrong or just deliberately misappropriate from something in the wrong way.  DevOps is something hot today and more and more companies what be part of the party.  If you are familiar with the Agile movement, something it happened with it before. There is no what or ever written on STONE DevOps Definition however for me it's 100% clear what DevOps is NOT:   - It's not a Tool   - It's not a Service   - It's not a Team   - It's not a Department   - It's not a Certification   - It's not a Role

Today i will show how to setup a complete VPC(Virtual Private Cloud) between 2 Data Centers in different Regions(I will use AWS Oregon and AWS N California) this is mandatory to test and run multi-data center solutions, we will need create a VPN(Virtual Private Network) over the internet, todo such a task we will use Open Swan . This task is very complicated and have several steps its easy to make some mistake and mess with everything so be very careful, the whole exercise could easily take 3h or more. Also want say thanks to my Friend Joao Palma(AWS Solution Architect) who supported me on this task :-) and have extreme patience and know-how on the hard-core devops amazon cloud things :-)

Let`s say you need monitor a box and see what happens in sense of CPU, IO, Network, Memory and you want see some nice charts? There is a great tool todo that is monitorix you can real good data and is very easy to get it running. Monitorix is very simple to use and have a very nice web interface . Today i will show how to install and run monitorix on Amazon Linux OS.

NTOP 2 is a great tool for linux monitoring. It`s focused on network and have all sorts of charts, visualization and network information you might need. Today i will show how to install and run ntop2 on Amazon Linux OS(CentOS based) this is not a straight forward task because there are lots of dependencies. This is very useful if you are doing Stress Tests or Network or Network Failure tests because you can see whats going on with plenty of details the whole thing is very colorful.

The IT-industry always got 1 thing of of 10 and just because they have 1 thing they think they got the point. I saw this with SOA, REST, Agile and now DevOps is happening too. Yes i will say one more time that the DevOps team is wrong. Is so wrong, is not just a name and is not just a matter of practices. More and more a see what the it industry got from DevOps is CLOUD and Automation - witch is great because this a very important aspects of devops but however devops is way more than that. The confusion a SEE is calling OPS -> DevOps, OPS is OPS, OPS is not DevOps. You have Dev in your company a most likely have a ITIL shared OPS in your company so lets say you have 100 developers mostly you have 20 DBAs.

Test is a very important part of software development. Everybody agree and some people(sadly not everybody yet) do lots of unit testing, some do integration tests other do some kind of UI testing as well. But thats not enought you are into SOA/microservice land. As much as you distribute your software you have way more wants to fail. Tests need to catch up, Stress test are something that unfortunately people dont do - sometimes they do but when they know that there is a scalability problem witch is sad. This practice of stress tests could be automated(it really should) or at least make sure you run periodically as far as i know Netflix does 2-3 times per week - because this is not just about scalability. Stress Tests are bigger than just how many users can i handle.

 Everybody is looking for the cloud right now. Amazon Web Services(AWS) is leading and MS is getting aggressive with OSS and cloud, I think google was never competitive with cloud. The cloud market is ultra-hot . However there are lot of side effects on this let's say cloud rush. The basic one is the fact if you have a low skill operator or low skill architect this guys are dead. Because today is pretty ready to have solid and great architecture almost for free using amazon AWS. Off course there is a lock in effect on this. Amazon strategy already migrate monoliths to the cloud using lots of cloud services, dont get me wrong this services are great but you have a big infrastructure lock in with this. And depending how you do in out application you can have application lock in as well because amazon is amazon is not a RFC or a JSR spec.

The world is changing. It's becoming more and more complicated. Systems are getting that as well, more and more real time, on-the-fly, available, concurrent, dynamic. If all that things are happening why we still suck when you talk about development and operations working together ? There is a old war between dev and ops, there're two worlds, two cultures, two totally different ways of thinking, concerns, there're 2 departments often with different managers, I don't talk about my company I talk about the majority of the world, there're this false dichotomy. Have you ever throw something over the dev or ops wall ? I did! It's amazing how still there're this wall and how dev and ops don't know how to work together effectively. Devs often think that the only that matter is teach ops how to restart the server and where put the God Damn EAR file. Ops often think there're is only life after QA. Both are totally wrong. If you have a stupid smal...
