Configuration management

Virtualization has provided a new challenge: hundreds, even thousands of virtual machines are impossible to maintain by hand. New systems need to be provisioned, configured, monitored and backed up on a daily, or even hourly basis, depending on the rapidly changing business needs.

This is where configuration management comes into play. New tools, such as Puppet, provide a vast ecosystem for managing this army of machines. In skilled hands a whole datacenter becomes an obedient servant of it's master to do exactly what the business demands, whether it is serving webpages, processing financial transactions or sending out millions of e-mails a day.

Here at Opsbears, automation is highly valued as it allows a single system administrator to manage as many as 80-100 physical nodes and an amazing 1000 virtual nodes.


Consulting

Setting up a new project? Unsure what hardware to get and how much man power you'll need? With the experience of more than a dozen high profile web projects and more than 10 years of professional experience estimating operational costs is one of our major strengths here at Opsbears.

Renting or buying, Infrastructure As A Service or System As A Service? Too many choices and not enough information is making the decision process harder, especially for a startup with little to no real world infrastructure experience. Opsbears helps by providing detailed recommendations and cost-benefit analysis on each solution.

Once you have your infrastructure, rapid deployment techniques help you on your way as you release your project to the general public.
