ORIGIN SHIELD
Absorb Traffic Spikes, Overcome Outages
Effortlessly offload web and video traffic to reduce backend costs and stay online when CDNs go down.
User Experience: Too Important to Leave to Chance
Stay Online, Always
Staying online is the name of the game.
Downtime is costly, and audiences deserve consistent quality of experience. Traffic spikes and CDN cache misses put pressure on backend web services, affecting performance and stability, and public CDNs can fail.
User experience should never be left to chance. An additional resilience layer makes all the difference.
Origin Shield
A Resilience Layer for Web and Video
Varnish Enterprise caching software sits in front of backend servers, accelerating web and video content, protecting infrastructure from traffic spikes and ensuring normal operations during outages.
As an origin shield, it minimizes calls to backend servers by being a collection point for incoming uncached requests.
From thousands of requests, only a few hit the backend. More stability, more uptime, more users getting the best experience.
Benefits
After deploying a Varnish origin shield, many enterprises find additional benefits even after it solves their primary challenge, whether that's resilience, performance or cost.
Active Defense
Shield web servers from peak loads and DDoS attacks.
Reduce Spend
Reduce egress and hardware needs with 10x less traffic reaching backend web services.
Keep Delivering
Serve web and video content during CDN outages to mitigate costly downtime and satisfy SLAs.
Stay Shoppable
Reduce risk cost-effectively and maintain uptime during critical, traffic-heavy periods.
Reduce Cache Misses
Catch The Content Public CDNs Miss
Cache misses increase when different CDN PoPs need identical content at the same time, or cannot cache certain data types like POST requests.
Varnish caches these misses, increasing cache-hit efficiency for more responsive web experiences and greater stability.
Seamless CDN revalidation. Protect infrastructure from the impact of revalidating CDN nodes.
Scalable security. Gain protection against intentional and unintentional attacks.
Reduce Egress
Make Cloud Affordable at Scale
Cloud origin services like AWS, Azure and GCP are reliable ways to deliver web content, but egress costs can become unsustainable as traffic increases.
Varnish Enterprise maximizes cache hits to reduce egress fees while delivering web content faster. A standard Varnish origin shield deployment sees a 10x reduction in backend traffic.
