Video: Why You Should Run Regular Health Checks To Ensure High Availability

In this video, Philip Merry, Software Engineer at SIOS Technology, talks about the importance of running health checks at a regular interval, especially when some system-wide changes are made.

A health check of your high availability (HA) systems is critical to ensuring business continuity. “Customers who get health checks benefit from the ability to predict and avoid issues in the future,” says Philip Merry, Software Engineer at SIOS Technology. “Customers who’ve implemented our recommendations and health checks also see fewer issues in the deployment activity and open fewer cases in the life of those nodes.”

In this video, Merry walks you through the process of health checks and explains how SIOS helps teams to ensure these health checks are smooth without any unexpected downtime. He also shares some recommendations as to how often these health checks should be done and how teams can prepare themselves for effective health checks.

5 Retail Challenges Solved with a Robust HA/DR Solution

September 19, 2023 by Jason Aw Leave a Comment

5 Retail Challenges Solved with a Robust HADR Solution

5 Retail Challenges Solved with a Robust HA/DR Solution

The retail industry is constantly evolving, driven by changing consumer behaviors and advancements in technology. Retailers rely on critical databases such as SQL Server, Oracle, MaxDB as well as POS applications and business analytics tools to stay competitive. High availability (HA) and Disaster Recovery (DR) solutions are essential to mitigating downtime for these IT operations and enhancing customer trust. Read on to learn the top five challenges solved in the retail industry with a robust HA/DR solution.

Challenge 1: Uninterrupted Operations in the Digital Age

With the rapid growth of e-commerce and the shift toward online shopping, retailers must ensure their digital platforms remain operational at all times. Downtime can lead to lost sales opportunities, erode customer confidence, and damage the brand’s reputation. A robust HA solution, integrated into the IT infrastructure and offers 99.99% availability by eliminating single points of failure.

Through the use of failover clusters, HA ensures that if an application fails – whether due to network, storage, server, or software issue or a disaster, the workload is automatically shifted to a functional secondary system, minimizing downtime.

Challenge 2: Data Protection and Security

The retail industry handles vast amounts of sensitive data, including customer information, payment details, and transaction histories. Protecting this data from breaches, or accidental loss is a rising and common concern. A comprehensive backup solution plays a crucial role in data protection by creating regular backups and storing them in secure, offsite locations.

In the event of a security breach or system failure, a robust backup strategy minimizes data loss. By restoring data to a previous state before the incident, retailers can continue operations with minimal disruptions.

Challenge 3: Protection from Natural Disasters

Whether critical operations are run in the cloud, or in on-premises data centers, they are susceptible to natural disasters such as hurricanes, earthquakes, or floods. These events can potentially cause immense losses and disrupt business operations. A well-implemented DR solution addresses this challenge by replicating data and failing over critical operations to a remote, geographically separated location.

In the face of a natural disaster that renders a primary data center inoperable, DR redirects operations to a secondary site that is geographically distant. Retailers can quickly recover and resume online services, minimizing financial losses and retaining customer loyalty. Having a robust DR solution in place provides retailers with peace of mind, knowing they can bounce back even in the worst-case scenarios.

Challenge 4: Mitigating Seasonal Workload Spikes

The retail industry experiences seasonal fluctuations in demand, especially during holiday seasons and special events. Preparing for sudden spikes in website traffic and transaction volumes is crucial to avoid performance bottlenecks and potential system failures. HA/DR solutions offer dynamic scaling capabilities that adapt to varying workloads.

During these high-volume periods, the cost and consequences of downtime can be devastating. Retailers need an HA/DR solution to ensure their key operations are protected from faults, failures, network outages, as well as local, sitewide, or regional disasters.

Challenge 5: Compliance and Business Continuity Planning

The retail industry is subject to various regulations related to data privacy and security, making compliance a top priority. A robust HA/DR solution aids retailers in meeting these regulatory requirements by ensuring uninterrupted operations.

Additionally, HA/DR solutions are instrumental in business continuity planning. Retailers can assess potential risks and develop comprehensive strategies to keep the business running in adverse situations. By conducting regular disaster recovery drills and testing failover mechanisms, retailers can identify vulnerabilities and fine-tune their response to potential disruptions, ensuring a swift and efficient recovery.

Making sure your retail business is resilient and customer-focused in today’s digital age demands a robust high availability/disaster recovery (HA/DR) strategy. It’s the key to dealing with everything from seamless operations and data protection to bouncing back after natural disasters, handling seasonal rushes, staying compliant, and keeping your business running smoothly. With the right HA/DR solutions in place, retailers gain the power to not just survive but thrive in a fast-paced market.

High Availability and Disaster Recovery Solutions for Applications in Google Cloud

Google Cloud Platform High Availability

SIOS DataKeeper is recognized by Google Cloud Platform (GCP) as the only high availability clustering solution that enables the accelerated delivery of high availability SQL Server clusters and other business-critical applications in GCP. SIOS DataKeeper enables Windows Server Failover Clustering (WSFC) environments to protect applications in GCP without the need for shared storage. With it, SIOS DataKeeper lets organizations run their important applications in the cloud without sacrificing the high availability and disaster protection they have come to expect from failover clustering environments.

SQL Server High Availability Cluster in Google Cloud Platform

Organizations are often prevented from moving their business-critical applications, such as SQL Server, to public cloud environments where shared storage – a prerequisite for failover clustering – is not available. By adding SIOS DataKeeper Cluster Edition to a WSFC environment, companies can create a high availability SANless cluster, eliminating the need for shared (SAN) storage and enabling customers to capitalize on the benefits of GCP. Companies can use SIOS DataKeeper with SQL Server Standard Edition to create a SQL high availability cluster without the cost of Enterprise Edition licensing.

Configure Clusters Across Environments

SIOS DataKeeper synchronizes local storage in each cluster node in real time using highly efficient block-level replication to create a SANless cluster that appears to WSFC as shared storage. SIOS DataKeeper provides the flexibility to configure clusters across physical, virtual and cloud environments, freeing IT to drive additional value to the business.

High Availability and Clustering Solutions for Applications in AWS

What is AWS Clustering?

AWS clustering ensures high availability protection for critical applications running in AWS EC2 environments by eliminating single points of failure. In an AWS cluster environment, two or more nodes in AWS are configured in a failover cluster using clustering software. The critical application is run on a primary node in the cluster. If clustering software detects an application operation failure, it orchestrates a failover of the application operation to secondary node(s) in the cluster.
