We work hand-in-hand with all of our other engineers to identify, resolve, and prevent complex system administration issues.

Cloud Consulting (Amazon, Rackspace, etc.)

The last two years have seen an explosion of demand for cloud based system administration experts.

Merely going to "the cloud" will not solve your performance issues if your application is not ready to scale and if your in-house team is not familiar with the latest cloud technologies from Amazon or Rackspace.

When we do sysadmin work in the cloud, we focus on:
  • Familiarity with leading technologies from Amazon and Rackspace
  • Amazon: EC2, S3, EBS, SES, ElastiCache, SimpleDB, CloudWatch, CloudFront
  • Rackspace: CloudFiles, CloudServers, CloudSites, Load Balancers
  • Potential cost savings versus your current environment
  • Aggregate cloud migration and onramping costs
  • Configuration of elastic load balancing and scale up/down rules
  • Performance impact or gain analysis (dedicated hardware vs. cloud)
  • Cloud-to-cloud or off-cloud backup and redundancy solutions
  • Diverse customer experience will help in determining which cloud has the features you need.
