Shared or dedicated infrastructure
Applications can be hosted together on shared infrastructure or independently on
dedicated infrastructure.
The following is main criteria in determining the right choice:
- If the application is mission critical and needs the most risk averse
infrastructure configuration, use dedicated infrastructure.
The following table lists both the infrastructure types:
| Infrastructure type |
Description |
|---|
| Shared |
Sharing infrastructure with other applications can save hosting costs
for applications of similar size and category. Server resources such as
memory are split equally amongst all applications. The biggest risk in
shared hosting is that one application can consume more of the
underlying resources and cause impairment to other applications.
Shared infrastructure can handle as many applications as resources allow. |
| Dedicated |
Dedicated infrastructure is free from other applications consuming
server resources. If the application is larger than the other
applications already hosted on a cluster, having dedicated
infrastructure makes sense. Security compliance may prevent an
application from being hosted alongside another. In addition, you can
leverage dedicated infrastructure, such as load balancers, to conduct
vulnerability scans and load tests. For more information, see
