How high availability and disaster recovery are expected to develop through 2022

From multicloud to new requirements for disaster recovery and high availability protection – here are some of the biggest trends which we can expect to see in 2022, according to SIOS Technology Corp.
While some well-established trends, such as the migration of applications and data into the public cloud, will continue in 2022, the ongoing potential for disruption caused by COVID-19 will drive IT to greater expectations for high availability (HA) and disaster recovery (DR).
Cassius Rhue, VP of Customer Experience, SIOS Technology, predicts the following major trends driven by these expectations:
Multicloud infrastructures will become mainstream - despite the added complexity of running different workloads in different clouds, a multicloud model enables organizations to choose cloud offerings that are best suited to their individual application environments, availability needs, and business requirements. Concerns about the ability to meet 99.99 percent SLAs in the cloud for business-critical applications will prompt companies to implement sophisticated application-aware high availability and disaster recovery solutions.
More investment in disaster recovery - climate change and social unrest have moved the need for disaster recovery to the forefront of IT focus. DR planning is no longer factoring in the rare “once in 100 years storm” or “once in a lifetime earthquake.” Companies will spend more on DR in 2022 and look for more flexible deployment options for DR protection, such as replicating on-premises workloads to the cloud and failover clustering across cloud availability zones and regions.
High availability protection for storage will become standard - simple backup of data storage is no longer sufficient. Regardless of whether the storage is NFS, SAN, cloud-native shared storage, or replicated local storage, companies will increase protection levels for their data storage – both on-premises and in the cloud - to include HA/DR protection.
Companies will reconsider public cloud hosting - some companies that moved business-critical applications into the public cloud are now considering either a reverse migration or a hybrid-cloud configuration for three main reasons: unpredictable cloud fees; data sovereignty requirements for companies that are subject to regulations that require them to keep data within their company’s geographic borders; and the need for in-house control over IT infrastructures.
Container complexity will limit adoption for production workloads needing HA/DR - containers are continuing to make the headlines and are destined to be used in more use cases throughout the IT infrastructure. The benefits of containers are proven in DevOps environments but their complexity, coupled with constraints on IT resources and the complex architecture of many applications, databases, and ERP systems will limit their adoption in production environments. Companies will continue to run complex applications, databases, and ERPs in on-premises and cloud environments where they can ensure HA/DR protection.
Enterprise reliance on databases and ERP systems will drive higher demand for specialized HA expertise - powerful database and ERP systems such as Oracle, SAP S/4HANA, and SQL Server have become so business-critical that even brief downtime for these systems is costly. They are running in increasingly complex environments, prompting more and more companies to turn to HA/DR specialists with deep, application-specific, experience in implementing uptime protection for these important systems.
