With all the technology approaches in the market place to modernize IT, it is a challenge to maneuver through all the noise and figure out which is the best approach for you and your company. Whether you are considering cloud, hyper-converged, revolutionary database products, or a new dev ops program, it all seems daunting. In recent conversations and blogs that I have read, any of these changes need to be accompanied by a change in cultural and skill set. The complexity of the changes and the impact they have on an organization reminds me of the process I went through to decide whether or not to modernize my existing home or buy new.
Modern hosting and service providers often face the challenge of managing the cost efficiencies of their platform. A common solution is to deploy a multi-tenant or multi-instance architecture in which many customers share the same hardware. The reuse of hardware over many clients drives down costs and also reduces the required ongoing administration.
Multi-tenant deployments host many clients in the same instance of software while segregating the client data through configuration. Multi-instance designs are similar but run one instance of software per client. To the storage tier, both approaches require many sub-ecosystems to run simultaneously in a shared space and will cause similar access challenges:
- Unpredictability of usage
- Height of individual usage spikes
- Scale versus storage performance (more clients translates into a more random and parallel workload)
