SOFTWARE ARCHITECTURE DESIGNDevOps & Reliability
Building a cloud native solution or adapting existing one to cloud. Design of globally reliable systems for 24/7 availiability in various geographic zones.
Function critical systems have to be available continuously 24/7 in spite of high user load and hardware damages. Luckily, DevOps processes and tools allow to build an infrastructure for your solution that is scalable and can quickly react to higher traffic and resource demand if necessary.
Reliability Design however concentrates on avoiding single points of failure in your infrastructure. A failure of one proxy server should not switch off an entire SaaS business. Similarly, a failed database should not take down a critical service frontend like banking site or insurance claim request system. Any part of a complex software solution should be redundant and replaceable in case of hardware or connectivity problems.
Typical software challenges we observe regarding infrastructure availability:
- Single point of failure at system entry like load balancers
- Single point of failure in utility features like cache servers, messaging systems, monitoring etc
- Only one location for infrastructure placement, typical for single cloud regions
- No disaster recovery plan in place with rehearsals
- No periodic backups with restore rehearsals
- No quick & automatic scaling for components and infrastructure provisioning
- No Know - How Management in support groups for effective production disaster risk mitigation
- No alerting of critical system components
If you feel that you suffer in your project due to these points, we can help.
What we can do for you:
- Analyse current risk profile for your production operations and prepare mitigation plan
- Prepare design for efficient reliable applications that are fully using modern DevOps infrastructure and can operate globally
- Create procedures for disaster recovery in production and train your team with them
- Introduce proper backup strategies for all components of your solution
- Create DevOps flows that will scale up infrastructure in case of hardware failure or higher resource demand
