SIOS Technology has been recognized by Amazon Web Services with the AWS Resilience Software Competency in the Design category — a signal that cloud customers are increasingly prioritizing architectural resilience as a first-class requirement, not an afterthought. The designation positions SIOS as one of the partners AWS trusts to help enterprises build and operate highly available, fault-tolerant systems in an era where outages can rapidly translate into customer churn or lost revenue.

For organizations migrating critical databases, financial applications, or transaction-heavy systems to AWS, the message is clear: resilience engineering now sits at the center of cloud-native strategy.

Why Resilience Is Back in the Spotlight

Distributed systems have always been prone to failure — from bad deploys and misconfigured infrastructure to data corruption, network partitions, or region-level outages. What has changed is the operating environment. Teams are shipping faster, architectures are more loosely coupled, and digital services now span multiple geographies and availability zones.

Even small disruptions can ripple across microservices, delay transactions, or cause compliance issues for regulated industries. That pressure has made resilience a board-level concern for banks, retailers, and enterprises running mission-critical workloads in the cloud.

AWS introduced its Resilience Competency to address this challenge, validating partners that can help customers design systems capable of recovering quickly from inevitable failures. SIOS earning the competency in the Design category indicates it has demonstrated both technical depth and real-world customer success in architecting for failure on AWS.

What SIOS Brings to AWS Customers

SIOS Technology, known for its high availability and disaster recovery offerings, provides a mix of software and consulting services that help enterprises implement predictable, automated failover strategies.

Its flagship components include:

• LifeKeeper, which delivers application-aware failover clustering. Instead of relying only on infrastructure triggers, the software monitors the health of applications themselves and shifts workloads when problems arise.

• DataKeeper Cluster Edition, which provides block-level data replication across AWS Availability Zones or Regions, supporting low-latency and geographically distributed deployments.

Together, the technologies aim to minimize both downtime and data loss — requirements that have become table stakes for workloads such as banking apps, trading platforms, ERPs, and large e-commerce systems. According to SIOS, these tools allow enterprises to “expect failure” while ensuring users rarely feel its impact.

Masahiro Arai, SIOS’s COO, framed the milestone as validation of the company’s role in strengthening cloud resilience for customers. He emphasized that performance expectations have shifted toward “always on, always available” services and that enterprises need proactive architecture, not reactive recovery, to meet those standards.

AWS’s Broader Push Toward Resilience Engineering

AWS has been steadily evolving its resilience framework, from Well-Architected best practices to a growing suite of resilience services. The AWS Competency Program is intended to give customers a way to identify trusted partners when planning complex migrations or re-platforming efforts.

The Design category in particular highlights partners that help teams build the foundation — architectures capable of absorbing, isolating, or rapidly recovering from failures. As more organizations re-evaluate disaster recovery plans, multi-AZ replication strategies, and cross-region failover policies, validated expertise has become more valuable.

Competency partners such as SIOS offer guidance ranging from initial assessment and architecture reviews to implementation support for resilience mechanisms tailored to a workload’s specific risk profile.

The Road Ahead

Enterprises are under growing pressure to prove that mission-critical services can survive failures without interrupting customer experience. As digital operations scale — and as regulatory scrutiny tightens for sectors like financial services — resilience engineering is becoming a competitive differentiator.

With its new competency, SIOS positions itself as a partner for organizations rethinking how they build and run core applications on AWS. For readers evaluating HA/DR strategies or planning cloud migrations, this signals increased maturity and optionality within the AWS ecosystem.
