 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.

On the previous posts i show how to use docker , docker-compose and nodejs with vagrant now let`s do a full jvm env :-) This setup is pretty easy and straightforward for you however it could take some time depending of your internet bandwidth because we gonna download several components. Remember you need to have Vagrant installed already, this time we gonna need more than just the Vagrant file because java, scala, clojure for instance require we setup environment variables so we gonna need change some files for clojure and sbt  in order to make everything work smoothly.

On the previous post i showed how to have docker and docker-compose with Vagrant . In this post i will show how to have a simple NodeJS environment with Vagrant. I will show how to install the most common solutions and frameworks for node like: npm , express , qunit , yo and much more. It`s very easy, you need to have vagrant installed, them just copy my Vagrantfile and create a directory called shared on the same folder you have copied my Vagrant file.  After that you are ready to rock.

Boot2Docker is great however it has some limitations. For instance the OS is readonly and came with pretty much nothing, setting up a shared folder in windows is challenging as well as i showed on last post .  In this post i come to show something different and easier than the previous solution. You can use docker with vagrant if you are a windows or mac user this is better than use boot2docker because IMHO you can do it easily and with less software and you also gain a linux os with you can do stuff because is not read only. Let`s use Vagrant .

Docker is ultra hot right now. It`s becoming a standard very quickly.  There are some issues on IO and Network but still a very promising solution for prime time. If you are a developer and are working on a Windows machine docker is great for you because you can have linux almost for free :-) For Mac and Windows users we need use Boot2Docker . Boot2Docker is a very small image lass them 30MB and is ultra fast it uses tiny linux kernel . Let`s see how to have a shared folder in windows and a docker container using ubuntu inside docker :-) This should be included at the official boot2docker image at some point but for now or you build the image or you do a workaround.

DevOps is not a tool, its not a service, its not a framework, its not a process, its not a role. DevOps is a state of mind and mindsets that your company wants get there to have better it performance.  This is hard and depends from culture and several aspects that are unique from company to company so there is no recipe for doing devops or right way.

Akka is a great tool. It has so many cool feature and very impressive performance. Today its one of the best technologies todo lightweight sync or async processing. Great for high frequency trading domains, onlime media, ads and financial. Even if your company is not in one of this domains you can benefit from akka, specially if you are looking for efficiency.  So whats the relation with Microservices architecture(MSA)? Microservices architecture powers distribution over centralization, thats leverage another aspect called Discoverability.
