Unlocking the Secrets of Uninterrupted IT Operations: Demystifying High Availability and Disaster Recovery

Zerto

In the challenging landscape of keeping your IT operations online all the time, understanding the contrasting methodologies of high availability (HA) and disaster recovery (DR) is paramount. What Is High Availability? While this architecture can ensure that the application is always online, it comes at a cost.

Using Route 53 Private Hosted Zones for Cross-account Multi-region Architectures

AWS Disaster Recovery

Route 53 Private Hosted Zones (PHZs) and Resolver endpoints on AWS create an architecture best practice for centralized DNS in hybrid cloud environment. This blog presents an architecture that provides a unified view of the DNS while allowing different AWS accounts to manage subdomains. Architecture Overview.

Implementing Multi-Region Disaster Recovery Using Event-Driven Architecture

AWS Disaster Recovery

In this blog post, we share a reference architecture that uses a multi-Region active/passive strategy to implement a hot standby strategy for disaster recovery (DR). This makes your infrastructure more resilient and highly available and allows business continuity with minimal impact on production workloads. This keeps RTO and RPO low.

Disaster Recovery (DR) Architecture on AWS, Part IV: Multi-site Active/Active

AWS Disaster Recovery

The architecture in Figure 2 shows you how to use AWS Regions as your active sites, creating a multi-Region active/active architecture. Each Region hosts a highly available, multi- Availability Zone (AZ) workload stack. I use Amazon DynamoDB for the example architecture in Figure 2. DR strategies.

Journey to Adopt Cloud-Native Architecture Series: #3 – Improved Resilience and Standardized Observability

AWS Disaster Recovery

In this blog, we talk about architecture patterns to improve system resiliency, why observability matters, and how to build a holistic observability solution. Due to its monolithic architecture, the application didn’t scale quickly with sudden increases in traffic because of its high bootstrap time. Predictive scaling for EC2.

IT Resilience Within AWS Cloud, Part II: Architecture and Patterns

AWS Disaster Recovery

In Part II, we’ll provide technical considerations related to architecture and patterns for resilience in AWS Cloud. Considerations on architecture and patterns. Resilience is an overarching concern that is highly tied to other architecture attributes. Let’s evaluate architectural patterns that enable this capability.

Disaster Recovery (DR) Architecture on AWS, Part II: Backup and Restore with Rapid Recovery

AWS Disaster Recovery

Every AWS Region consists of multiple Availability Zones (AZs). A Multi-AZ strategy, which replicates resources across AZs, is necessary to provide high availability (HA). In Figure 5, we show a possible architecture for detecting and responding to events that impact your workload availability. Related information.
