MongoDB supports master-slave replication and a variation on master-slave replication known as replica sets. Replica sets are the recommended replication topology. What is the difference?
Replication vs. Replica Set
MongoDB’s replication is “single-master”, meaning only one node can accept write operations at a time.
In a replica set, on the other hand, if the current “primary” node fails or becomes inaccessible, the other members can autonomously elect one of the other members of the set to be the new “primary”.
Layershift were the first provider to introduce this revolutionary platform to the UK. Now we’re first to go multi-region with the addition of our USA Southwest region in Phoenix, Arizona.
Answering your demand
Customers throughout Europe are enjoying the exceptionally high standard of service and support we deliver together with our Jelastic PaaS. More and more businesses are saving time and money by only paying for usage, rather than instance size, combined with the renewed focus our highly versatile hosting platform grants by removing sysadmin setup time and headaches.
But our friends across the pond in America were sad. They looked across with envy and pleaded:
“Why do we have to put up with poor service and unreliability from the huge IaaS corps?”
Of course this illustrative of the problem facing most of our PaaS competitors: almost all are built on top of third party infrastructure such as AWS, Digital Ocean, or Azure, so they really have no control over the important infrastructure details; nor can they provide robust SLAs as standard like Layershift.
The US is also an important market for many of our European customers. Together these factors created a very high demand to combine Layershift’s extra special service quality, scalable hosting platform, and a well connected US server location.
We took this opportunity to expand our overall footprint – already in Manchester, Amsterdam, Chicago, and Singapore – launching our Jelastic PaaS in Phoenix is a really proud moment for us.
Today’s businesses are addicted to IT. Every part of the business now needs Internet connectivity to function, and not just for cat videos during breaks; from communication via email, instant messaging, and VoIP, to back office ERP and CRM – not to mention the importance of digital marketing channels and ecommerce.
Applications, and even consumer-facing services, are now shifting to cloud and hybrid models as companies realise that in-house IT, once tasked with running an Exchange server and maintaining desktops, lack the tools and specialist expertise to keep these systems running.
Our heavy dependence on the Internet to get business done exposes a threat with the potential to transform the competitive advantages of this new world of doing business in the cloud into a business killer.
