5 Top Solutions for Fast, Scalable Web Content Replication

5 Top Solutions for Fast, Scalable Web Content Replication

Most traditional file replication solutions aren’t designed to handle the workloads required of modern app and web content replication deployments. Not only do these solutions experience frequent breakdowns and replication delays that can harm the user experience, they aren’t designed to optimally handle large deployment schemes — e.g., synchronizing content (web content, software updates for apps, etc.) across many web servers as fast as possible.

In this article, we’ll discuss what to look for in web content replication software as well as five excellent solutions for large replication deployments — starting with our own solution for web and app server synchronization, Resilio Connect.

Resilio Connect is an organically scalable web content replication solution that can quickly detect and replicate files and file changes in real-time. It uses a P2P transfer architecture and WAN optimization technology to deliver some of the fastest replication speeds in the industry (10+Gbps). Resilio Connect has been proven to handle synchronization jobs of 250+ million files, and can update hundreds of servers in about the same time that it takes to update one server.

What to Look For in Web Content Replication Software

In order to maintain data availability and keep your site users happy, you need a web content replication solution that meets the following criteria:

High replication speed 

Your solution must replicate files quickly so users across your entire replication environment have access to the most current version of files. 

For example, if a user changes their profile picture on a dating site, all other users accessing the website on any server across the world should immediately have it. The replication speed of your solution will be largely determined by how it replicates files (i.e., replication topology, replication methodology, and more) and other methods and technology that speed replication.

Good scalability

Your solution should easily scale to handle your site replication needs, whether that means replicating large files, a large number of files (i.e., many millions of files), or replicating to a large number of endpoints.

Many organizations also require a solution that can replicate files in different directions — i.e., one-to-one, one-to-many, many-to-one, many-to-many, or N-way synchronization. Regardless of the replication direction, your solution should be able to handle your sync needs in a fixed, suitable time-frame.

Fast replication over WANs

For deployments with web servers spread out across geographic locations and/or using high-latency, unreliable networks, fast replication over WAN networks is a must. Many replication solutions aren’t optimized for WAN transfer, resulting in replication errors (i.e., lost packets) and delays. 

Your solution should include WAN optimization technology and be able to quickly replicate content over any network to reliably deliver files to their destination.

Resilience & reliability

Replication environments can be plagued by unreliable networks, hardware failures, software failures, and more. Overcoming these challenges with traditional replication solutions requires spending a lot of time and money developing complex disaster recovery systems (backup systems and servers, failover strategies, etc.). Choosing a reliable web content replication solution can save you time and money and ensure the uptime and availability of your web content.

Resilio Connect

Resilio Connect homepage: Universal file delivery that powers the world's most creative games

Resilio Connect is an enterprise-proven, real-time file replication and synchronization solution that uses a P2P (peer-to-peer) transfer architecture and proprietary WAN optimization technology to quickly synchronize, distribute, and consolidate files over any network. Because it uses a mesh, P2P network to replicate files, Resilio can organically scale to support the requirements of any large deployment — i.e., replicate files of any size, replicate large numbers of files (tested at 250+ million per job), and replicate to tens of thousands of endpoints.

Resilio Connect can perform file synchronization, consolidation, and distribution. It’s used by leading websites, such as Kaspersky, Match.com, and MixHits Radio.

P2P architecture for fast, reliable synchronization

Resilio’s P2P transfer architecture is one of the most notable features that set it apart from competitors with regard to replication speed and reliability.

Most other replication solutions use one of two replication topologies:

  • Client-server replication: In a client-server replication topology, one device is designated as a hub server and the other devices are designated as clients. The hub server can replicate files to any device and receive files from any device. The clients can only replicate files to the hub server, but can’t communicate with other clients. In other words, all replication must first go through the hub server. So if Client 1 wants to replicate file changes across your entire environment, it must first send those file changes to the hub server, which will then replicate the changes to all of the other clients one by one.
  • “Follow-the-sun” replication: In a “follow-the-sun” replication topology, replication occurs from one device to the next sequentially. So if Device 1 wants to share file changes with the other devices in your environment, it will first share those changes with Device 2. Device 2 will then share the changes with Device 3, and so forth.

Both of these topologies create bottlenecks in your replication workflow, as replication can only occur sequentially between two devices at a time — either from the hub server to one of the clients devices (in the client-server model), or between two devices (in the “follow-the-sun” model).

With P2P replication, however, every device in your environment is equally privileged. So if Device 1 wants to share files with Device 3, it can do so without first going through a Hub-Server.

Resilio Connect also uses a process known as file chunking. When sharing a file, Resilio will split that file into several chunks that can each transfer independently from the others. This enables all devices to share files simultaneously, resulting in transfer speeds 3-10x faster than traditional replication solutions.

P2P vs Client-Server architecture

For example, let’s assume you need to replicate a file across seven devices. Resilio will split that file into five chunks. Device 1 can share the first file chunk with Device 2. Once Device 2 has received that first file chunk, it can begin sharing it with Device 3 before it has received the entire file. Every device in your environment can share file chunks with any other device, so all of your devices can work together to speed up file transfer.

P2P file transfer also means that there is no single point of failure in your entire environment. In a client-server topology, replication is entirely dependent upon the hub server, which must be online and functioning at all times in order for replication to work. This requires organizations to invest in complex and costly failsafe setups (i.e., backup servers, failover operations, etc.) to ensure their system never goes down and web content distribution can always occur. Even then, replication is inhibited by:

  • The bottleneck created by the need to cloud-hop — i.e., sending a file to the hub server before sending it to the target device.
  • The slowest link between the source device and the destination device, as well as any latency that occurs across the end-to-end transmission.
  • File size limits.

In a “follow-the-sun” topology, replication can be impeded by any single device in your environment. If, for example, one device is on a slow or unreliable network, all of the other devices must wait for replication to complete on that device before they can receive any files.

These problems are magnified when replicating large amounts of data across many endpoints. With sequential synchronization, large syncs take a long time and data may not be available across all servers when requested (i.e.,  app users or website visitors will see broken links and missing images on web pages where the server hasn’t yet received the updated files).

But in a P2P architecture, any device can receive the necessary service or files from any other device in your system. If one device is on a slow network (or if the network goes down), the services and/or files can be supplied by a device on a faster network. Your replication environment will never fail because it’s not dependent on any single device.

WAN acceleration for optimized WAN transfer

Most web content replication solutions use transfer protocols that aren’t optimized for transfer over WANs. 

WANs are characterized by high-latency and varying degrees of packet loss. Many replication solutions use TCP/IP transfer protocol for transfer over both LANs and WANs. While TCP/IP works well over LANs, it responds poorly to WAN transfer.

For example, when packet loss occurs, TCP/IP treats it as a network congestion issue and will reduce the bandwidth for transfer over the network (i.e., reduce transfer speed). But since packet loss occurs frequently over WANs and is not due to network congestion, this is a poor strategy.

Resilio, on the other hand, uses a proprietary WAN optimization technology known as Zero Gravity Transport™. ZGT optimizes WAN transfer by:

  • Creating a uniform packet distribution over time.
  • Using interval acknowledgements for a group of packets (that also contains information about lost packets), rather than sending acknowledgements after every packet receipt.
  • Using delayed retransmission of lost packets to increase transfer speed.
  • Using a congestion control algorithm to calculate the ideal send rate and avoid overloading the network.

Learn more about how Resilio helped MixHits reduce their workload by 60+ hours per month.

Organic scalability and N-way file replication

As mentioned earlier, larger replication workloads (i.e., replicating large files and a bigger number of files) can result in synchronization delays and affect data availability across your environment with traditional replication solutions. These issues can be compounded by complications in your replication system — i.e., hardware failures, network failures, downtime for maintenance, etc.

But Resilio Connect is an organically scalable web content replication solution that actually enhances performance as your environment and replication needs grow.

For example, the more endpoints you add to your system, the faster replication will occur. You’ll have more servers taking part in replication, and Resilio can balance the load across multiple servers to avoid overtaxing any single network or device. 

In a 1:2 transfer scenario, Resilio Connect will transfer 50% faster than any dedicated server solution. That increases to 500% faster in a 1:10 transfer scenario.

Resilio Reduces Time to File Access

And Resilio is an enterprise-proven solution that’s designed to handle large deployments. Resilio can replicate files of any size over any network, and has been tested and proven to replicate 250+ million files per job.

With its P2P replication architecture, Resilio can replicate in any direction required, such as one-to-one, two-way, one-to-many, many-to-one, many-to-many (aka N-way sync). This is particularly important when replicating content across many geographically distributed endpoints, as all devices can take part in replication simultaneously and quickly synchronize data so it’s available across your entire environment.
