5 Ways to Improve High Availability and Limit Downtime Exposure

Organizations exclusively depend on IT infrastructure availability. This is why maintaining high availability 24 hours a day is crucial to ensure that its services are always available whenever needed. Likewise, data breach can greatly impact an organization and its finances, which can result to loss of customer trust and confidence.

Despite awareness of the risks, many still fall victim to data breaches which significantly impacts their revenue. Even the well-protected systems fail from time to time. In fact, the 2016 Cost of Data Breach Study published by Ponemon Institute, shows that the average total cost of a data breach is $4 million up by 29 percent since 2013.

This figure raises a growing concern over protecting the data organizations own, process and store. Fortunately, there are steps you can take to limit downtime exposure and it’s not only a matter of building the right facility infrastructure, but is about how the facility is operated and monitored on a daily basis as well.

To help you with, INOC, a global leader in the NOC services industry, will explain five ways to improve high availability and in result, limit your organization’s downtime exposure.

1. Application-Level Routing

During an occasion of transaction failure, cloud-aware applications can be modified to route transactions to a secondary service point. Failed transaction queries are automatically forwarded and reprocessed at the secondary working location. The adaption of application-level routing improves end-to-end network performance and reduce transit cost.

2. Monitoring

A monitoring service integrates an existing data center infrastructure and facilities management to provide an overall insight on daily operations. This monitors error-rates that exceed a predefined threshold to easily address issues and initiate self-repair.

3. Multi-Site Configurations

Multi-site configurations allow organizations to create a network of sites. In the event of hardware failure, the entire system can be redeployed to a secondary location in minutes. In this situation, the additional site would be a completely independent data center that hosts an independent copy of the primary site system. It is ideal for organizations that cannot tolerate downtime in their server.

4. Network IP Management

Network IP Management provides a centralized IP management which deploys a published service IP from one machine to another. This is identified as a self-healing process, where two servers monitor one another. If one of the server malfunctions, the other will assume its roles and processes. Linux provides such functionality with its Linux-HA suite.

5. Stateless Transactions

In a stateless model, no session or status information are retained by the sender or receiver. A server only keeps ongoing transactions, but after it is completed, any server that malfunctions have no effect on the state of historic transactions. This prevents clients to store permanent state, transactions, inventory or user data on an individual server to ensure that no session is interrupted due to hardware or system failure.
