Configuration review
Examine the relevant Nginx and Varnish configuration, request handling, and boundaries between components.
SERVICES / SERVER INFRASTRUCTURE AND PERFORMANCE
A clearer picture of what runs underneath.
Your application depends on more than its code. JetHost reviews and implements the server-side configuration that connects visitors, proxies, caches, and origin systems.
Understand the problem
before choosing the solution.
When traffic exposes a weak point, changing settings without understanding the request path can create new problems. Start with the environment, the symptoms, and the behaviour that needs to improve.
POSSIBLE SCOPE
What the work can include.
Reverse-proxy architecture
Plan how incoming traffic reaches the right application and how responses return to the visitor.
Cache strategy
Identify content eligible for reuse, define freshness and invalidation rules, and keep private responses out of shared caches.
Bottleneck investigation
Use available logs and agreed observations to investigate where work is waiting, repeating, or failing.
TYPICAL DELIVERABLESWork you can review.
Work you can review.
A handover you can use.
- A summary of the current request path and identified issues.
- An agreed implementation plan with dependencies and validation criteria.
- Reviewed configuration changes within the agreed scope.
- Relevant test observations, documentation, and handover notes.
Agreed scope. Deliberate steps.
We assess the environment, agree the intended change, implement within authorised access, and compare the result against agreed checks. Production windows, backups, rollback arrangements, and ongoing support are established in the project scope.
How an engagement worksBEFORE WE BEGIN
A few useful answers.
Can you review an existing setup?
Yes. Start with the symptoms, a description of the environment, and the relevant components. Access and any production changes must be authorised and scoped.
Does every project need both Nginx and Varnish?
No. Each component should have a clear purpose. A simpler configuration may be appropriate for your application.
Will changes require downtime?
That depends on the environment and the work. Change windows, operational risk, and rollback arrangements are discussed before implementation.
