We have expertise in AWS infrastructure management/DevOps operations, we work 24x7x365 and designed development / staging / production environments for our clients where the code is on github, and deployments can be in a automated script that checks-out code, runs grunt build, then switches to the new version. We can do rolling upgrades where the server is setup / tested, and switched to, once testing is complete. We manage over 300 servers on AWS including 4 Elasticsearch clusters , 4 Cassandra clusters and 4 nodejs apps.
