Application Delivery and Availability

Applications that remain fast, reachable and available when individual systems fail.

Where this helps

Business applications need to be reachable, responsive and protected. We design the infrastructure between users and applications so traffic reaches the right system safely and reliably.

Application delivery uses load balancers, reverse proxies, TLS and health checks to direct traffic. Layer 4 decisions use network information. Layer 7 decisions understand web and application requests, allowing more precise routing and protection.

Decisions we clarify
  1. 01Why does an application become unavailable when one server fails?
  2. 02How should traffic be distributed across sites or cloud environments?
  3. 03Where should TLS certificates and encryption be managed?
  4. 04How can we publish an application without exposing it directly?
  5. 05Is poor performance caused by the application, network or delivery layer?
Service blueprint

What we can design, deliver and operate.

Choose the depth you need, from a focused work package to a complete lifecycle engagement.

01

Application delivery architecture

Design the path between users and applications for performance, security and resilience.

  • Datacenter, private cloud, public cloud and hybrid designs
  • Application dependency, traffic and failure point mapping
  • Layer 4 and Layer 7 delivery architecture
  • Traffic policy, health checks and capacity planning
02

Load balancing and publishing

Publish applications safely and keep traffic moving when systems change.

  • Load balancing, session management and health checks
  • Reverse proxy and URL routing
  • Internal and external application publishing
  • Active active and active passive availability
  • F5 BIG IP and NGINX Plus implementation
03

APIs, performance and global traffic

Make application traffic easier to control, observe and optimize.

  • API gateway and API traffic management
  • Connection management, caching and protocol tuning
  • DNS based traffic management and geographic routing
  • CDN integration and multi site delivery
  • Application performance troubleshooting
04

TLS, migration and support

Carry delivery infrastructure from design to stable operations.

  • TLS policy, certificate deployment and renewal automation
  • Legacy ADC and platform migration
  • Application onboarding and production validation
  • Monitoring, upgrades, capacity and configuration review
  • WAF integration and secure delivery controls
Our role
