What is scalability? It's the ability to quickly accommodate a huge increase in traffic, hits or users, without performance degradation.

How do you make sure your setup is scalable?

• Scalable software architecture.
• Scalable network infrastructure.
• Scalable hardware infrastructure.

Sadly, none of these is usually thought out with scalability in mind. Most of the time, scalability is not a real issue, because success is a rare encounter. Still, you have to be prepared.

Appnor has the experience of adapting setups of 10,000 users to 1,000,000 users in months, managing sites with millions of hits per month or handling spikes or 10,000 or more connections per second.

Appnor's scalability services cover

• Designing scalable setups.
• Patching running setups to handle up to 100x traffic or load.
• Building clusters, load balancers and highly available setups.

Clusters are used for availability and scalability

• Highly Available Cluster: When a server (node) in the cluster fails, the cluster transparently moves the workload from the failed node to the rest of the nodes.
• Highly Scalable Cluster: When the overall load exceeds the capabilities of the nodes in the cluster, additional nodes can be added to it.

Facts about managed clusters

• A cluster has a minimum of 2 nodes and can expand up to thousands
• Nodes can be active or passive, working or just waiting to replace a failed node
• Commodity servers are used as nodes; the magic happens through software
• Fast networking and good storage are keys to a good implementation

Appnor's Clustering Services

We can help you implement any type of cluster you need, from simple high availability clusters with 2 nodes to high performance computing clusters (HPC). We have done this for all sort of customers, from e-shops to banks and weather simulation state agencies.
