Live Vertical Scaling
Resource management in real time
Scaling up without rebooting—flexible and cost-efficient
Live Vertical Scaling to absorb traffic peaks
Scenario in a physical data center
Vertical scaling of RAM and CPUs at the push of a button
All it takes to add resources to your server in the Compute Engine is operating a slider. The Data Center Designers (DCD) graphic interface lets you increase cores and RAM in very small increments.
This is possible because you are working inside a Software Defined Data Center (SDDC). The capacities for your virtual data center are sourced from within the physical data center’s hardware pool. This means that we can deploy new capacities in real time (software-controlled), whenever you need them. This procedure allows vertical scaling on the fly, i.e. adding new CPU cores and more RAM. You can add up to 62 cores and 240 GB of RAM (AMD CPUs) for each VM, or 27 cores and 120 GB RAM for Intel CPUs.
Scale up—vertical scaling for quick availability
Scaling up, i.e. the vertical addition of server resources, works smoothly irrespective of which operating system you happen to be using. MySQL registers the new capacities without requiring modification. In other words, you can immediately benefit from the boost in performance. This is an advantage over scale out, i.e. horizontal scaling by adding more server instances: horizontally scaled infrastructures are more complex, sometimes require extensive and therefore costly code modifications, and can’t increase performance in a fully linear fashion.
We provide you with a free Ubuntu-based operating system image to make sure that the convenient server management also works without a hitch on your virtual servers in the Compute Engine. On Linux servers, it is possible to use ACPI (Advanced Configuration and Power Interface) events to signal to the system during live operation that new processor cores were added. This means that the system does not have to be rebooted—physically or virtually.
Cutting costs with Live Vertical Scaling: pay-per-use
Server management using an API interface
Managing your virtual data center does not require use of the Data Center Designers (DCD). Thanks to our Cloud-REST-API, you can access the entire configuration even without the graphical user interface. For instance, you can write scripts to automate your scaling, e.g. throttle the system performance at night to release unneeded capacities. An effective way to save money! In our DevOps community, you will find a large number of microservices that let you automate your infrastructure just the way you need it.
