Varnish Origin Shield is a software-based caching layer that sits between your origin and CDN edge servers. It reduces the amount of traffic hitting the origin, caching requested objects and quickly serving them onwards.

Why Your Web Service Needs an Origin Shield

Improve Performance and Reduce Costs by Shielding Your S3 Buckets

For latency-sensitive workloads, like streaming video and CI/CD pipelines, low latency matters. Enter: the private CDN.
 
Join us in this webinar, featuring experts Thijs Feryn, Technical Evangelist at Varnish Software, and Charlie Lane, Principal Solutions Architect at Equinix, as they discuss how companies today are taking advantage of a private CDN hosted on a dedicated cloud offering to optimize their productivity and improve overall security and performance.
 
Why use a private CDN? For starters, the network, servers and the way you run the software all belong to you. Additionally, you have complete control and the ability to customize things the way you want them.
 
- Join us to learn how using a private CDN that is fully tailored to your needs can:
- Improve performance and quality of experience
- Increase scalability with your CDNs handling increased traffic without affecting performance
- Ensure reliability with redundant servers for high availability
- Optimize security thanks to CDNs protecting against DDoS attacks and providing SSL and encryption

The Advantages of a Private CDN

For the financial sector, out-of-date content, including incorrect trading and banking information is unacceptable. By not showing the most up to date content there is the risk of both enforcement actions by regulators as well as reputational damage in the eyes of customers and investors.

Caching the right content is a crucial part of web acceleration and content delivery solutions. However, keeping objects in the cache for too long can have even more severe consequences. Data inconsistency being one of them.

Leveraging cache invalidation helps businesses to stay compliant with EFTA & Regulation E, avoiding the risk of fines and fees, and even criminal liability in some cases.

Join our webinar to learn how to enhance your cache invalidation strategy to stay compliant and reduce costs.

How financial institutions can leverage cache invalidation to stay compliant

Did you know that removing objects from the cache is just as important as storing objects in the cache? Keeping objects in the cache for too long can result in data inconsistency.  Imagine breaking news not ending up on a news websites because the homepage is cached. 

Luckily Varnish has some built-in invalidation mechanisms to allow applications to forcefully remove objects from the cache. 
 
In this webinar we'll talk about: 
 - Purging
 - Soft purging
 - Banning
 - Secondary key

APAC: Cache Invalidation: What it is and How to Implement It

The web is used for more than websites & API calls these days: video content, DevOps artifacts, software updates and more are distributed over HTTP. For latency-sensitive workloads, like streaming video and CI/CD pipelines, low latency matters. Enter: the private CDN.


Experts Thijs Feryn, Technical Evangelist at Varnish Software, and Charlie Lane, Principal Solutions Architect at Equinix, discuss how companies today are taking advantage of a private CDN hosted on a dedicated cloud offering to optimize their productivity and improve overall security and performance.


Join us to learn how using a private CDN that is fully tailored to your needs can:

Improving DevOps Productivity & Security with Private Content Delivery

Varnish is the world's most powerful and flexible HTTP cache that is used to accelerate more than 10 million websites globally. A big part of its attraction, besides its industry leading performance, is the Varnish Configuration Language (VCL).

VCL is a domain-specific programming language that powers Varnish. It is used to configure the caching policies and to control the way Varnish interacts with both the client and the origin web server.

Having a full-blown programming language to describe the configuration of your cache gives you unparalleled flexibility to tune the behavior of the cache to your exact needs.

In this webinar you will learn the basic syntax of VCL, the way VCL controls the behavior of Varnish and some common use cases.

We'll teach you how to inspect and modify incoming requests, create policies to bypass the cache, control the time to live of cached objects, modify responses, manage cache variations, make decisions on the edge and many other tips and tricks that allow you to go beyond the capabilities of HTTP's built-in caching mechanisms.

Thanks to VCL and the rich ecosystem of Varnish modules (VMODs) you can go from caching on the edge  with Varnish to full-blown edge compute.

If your CDN fails, your website drops offline, taking your audience and revenue with it. 

In this webinar we’ll show how an origin shield can save you in an outage, so you can keep reaching your audience while other websites go down. 

As a caching layer between your servers and CDN, an origin shield also protects against the traffic impact of revalidating CDN nodes. They can even serve content if the origin itself goes offline.

Discover the easy way to defend against downtime and learn how to:

- Serve web content when your CDN fails
- Protect origin servers from high traffic
- Implement an origin shield, including sizing
- Maintain uptime as your origin fails
- We're also doing a live demo of a CDN outage to show manual and automatic failover strategies using an easy-to-implement Varnish solution
