Varnish Software’s powerful caching technology helps the world’s biggest content providers deliver lightning-fast web and streaming experiences for huge audiences, without downtime or performance loss.

Protect Your Performance, Network Latency, and Costs.

S3 is the de facto standard for object storage in the cloud. It is known for its scalability, global availability, ease of use, and pay as you go payment model. So why do you need to shield your S3 buckets? Two main reasons: performance & network latency, and cost. We dive into this and more in our latest video.

Join Varnish Technical Evangelist, Thijs Feryn, to learn about S3, why you should shield your S3 buckets, and how to get started as he covers:

- What is S3 and why shield your S3 buckets
- How an S3 shield works
- Why use Varnish Enterprise as your shield

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For the financial sector, out-of-date content, including incorrect trading and banking information is unacceptable.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

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:


Improve Performance: Faster object delivery due to proximity to users.
Increase Scalability: CDNs handle increased traffic without affecting performance.
Ensure Reliability: Redundant servers ensure high availability.
Optimize Security: CDNs protect against DDoS attacks and provide SSL and encryption.

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.

Cache Invalidation: What it is and How to Implement It

Almost all organizations rely on some form of content delivery. From websites to media to software. The transfer of data, internally and externally, over HTTP has been critical to the digital transformation of every industry. Historically, organizations turned to Content Delivery Networks (CDN) to serve these needs, however, the CDN market is consolidating as service providers of every size struggle to monetize traditional infrastructure that once was modern. 


All organizations that currently rely on CDNs need to take a very close look at what their options are if their primary CDN decides to exit the market. Due to advancements in Content Delivery Software (CDS), organizations that currently rely on traditional or modern CDNs should consider adding Private Content Delivery. This webinar will define the components of a CDN, and how advancements in servers, Infrastructure-as-a-Service (IaaS), and content delivery software now enable cost-effective, easier to manage private content delivery.

APAC: What Private Content Delivery is and Why it Matters

Every second counts. Slow artifact retrieval and Artifactory bottlenecks can damage productivity and delay business-critical software development tasks. At enterprise scale, the challenge only gets more complicated, with additional infrastructure, traffic and licensing overheads also putting the brakes on business growth.

On the other hand, DevOps teams that can get up and running quickly every day are ones that thrive.

This webinar session will dive into the challenges of managing artifacts at scale and why accelerating these processes is crucial in today's automated CI/CD pipeline environments. Varnish Technical Evangelist Thijs Feryn will take us through how caching can be used to optimize DevOps workflows through applications like JFrog Artifactory. He will cover how innovative development teams have leveraged caching to reduce developer wait time by up to 80%, improve performance by up to 25% and reduce costs by up to 20%.

Wherever you fit into the software development supply chain, this webinar will equip you with knowledge and strategies to improve your organization's DevOps efficiency and reduce operating costs. Don't miss this opportunity to learn how to leverage Varnish for optimal Artifactory performance!
