Tessell database services consist of three primary components that can be adjusted for scaling: Storage, CPU, and RAM.
Resize Database Configuration (Vertical Scaling)
With Tessell, Resizing can be done for vCPU/Memory or storage.
Compute/Memory resize
Go to My Services -> Select the required database -> Click Action -> Choose Resize -> Choose Compute required.
Click Save to resize the database. This resize restarts the database and takes a while.
Modify storage required
Go to My Services -> Select the required database -> Click Action -> Choose Resize -> Choose Storage
Click Save to resize the database. This resize restarts the database and takes a while.
Read Scalability
One way to scale performance without incurring downtime is to offload reads to the replicas by adding read replicas to your primary instance. This method enables you to free up write capacity on the primary server.
Adding a replica instance does not incur any downtime on your primary instance and is very easy from the Tessell console.
Add Read replica
Go to My Services -> Select the required instance -> Click Create Replica -> Choose Read Only Replica
