In a sea of options, most popular data replication solutions boil down to two types; synchronous, and asynchronous. While each option has its perks and drawbacks that will be covered further on, asynchronous, peer-to-peer data replication technology such as the Rapidi Replicator offer customers affordable, robust, and fully scalable solutions for their data management needs.
So why is it so important for organizations to invest in data replication technology? Solutions such as the Rapidi Replicator don’t only allow companies to get back on their feet in the wake of a catastrophic system failure, but also streamline day-to-day operations. Read on to find out how data replication technology can give your organization the cutting edge it needs to leave competition in the dust.
Important Differences Between Synchronous or Asynchronous Data Replication
The primary difference between synchronous and asynchronous replication solutions comes down to the time in which the data replica is written. In synchronous solutions, the primary and the replica(s) are written simultaneously. In asynchronous solutions, data is written to the primary server and then to the copy, so timing is staggered.
You may be tempted to believe that synchronous replication is categorically better because of how immediate the dissemination of data can be. However, asynchronous replication is far more bandwidth efficient, and the most expedient solutions can register alterations to your data in near-real time. Not to mention, asynchronous solutions tend to be more resilient to viruses and more affordable for smaller businesses lacking the deep pockets of the industry titans.
Peer-to-peer replication solutions take these perks a step further by offering the highest range of flexibility and modality; in peer-to-peer replication, data can be altered on any of the involved servers and the changes replicated to all other participating servers, making them equally important and therefore “peers”—hence the name.
The Perks of Peer-to-Peer Asynchronous Replication:
- Replication that must traverse long distances has a greater risk of suffering from latency, a kind of lag which can negatively affect applications. Latency is an issue for synchronous replication processes because synchronous replication banks on simultaneous data alteration. Asynchronous replication, though it occurs in near-real time, is far less likely to suffer from latency due to the staggering of data transfer.
- Peer-to-peer asynchronous replication tends to be quite a bit more cost-effective. Synchronous data replication tends to be expensive due to the technical needs necessary for simultaneous data synchronization to occur.
- Peer-to-peer replication solutions are more compatible with a wide variety of applications.
- Peer-to-peer replication solutions are less vulnerable to viruses. The staggered information transfer means that there will only be a noticeable disruption to services if both the primary and replicated data sets all fail. This naturally makes them the more resilient option.
- Peer-to-peer replication technology is almost always sold as a software-as-a-service, requiring no additional hardware.
- Peer-to-peer replication technology is the least taxing on available bandwidth, because of the staggered data transfer. Synchronous replication solutions generally require LAN bandwidth between involved servers.
Other Asynchronous Replication Options
Peer-to-peer replication involves a network of servers, also known as nodes, that are each able to function as a standalone server and replicate data changes between each other. They are “equal” in that information can be altered on any one of them, and be reliably replicated out to all others involved.
Another asynchronous replication topology is the “master-slave” replication solution, in which data changes to the “master server” or “master node” are propagated outwards to the “slave” servers or nodes, which are read-only, and cannot themselves be altered.
There also exists replication setups in which writable secondaries are not situated as equal peers; data manipulation can be submitted through any server, but are only processed by the primary server, and the results propagated outwards from there.
