Introduction Customers use multi-region architecture to achieve application resiliency such as Active-Active or Disaster Recovery (DR). Depending on DR strategy, customers may need to have failover from one region to the next. DR strategies are covered off in detail in a prior AWS Blog. DR strategies include either an Active/Passive or Multi-Site Active/Active approaches. Active/Passive […]

Update – 3rd May 2023 With this update, zonal shift for Amazon Route 53 Application Recovery Controller is now also available in the following AWS Regions. Learn more in the updated What’s New post or zonal shift documentation. Today we’re introducing zonal shift, a new capability of Amazon Route 53 Application Recovery Controller (Route 53 […]

Introduction: AWS Gateway Load Balancer (GWLB) is an Elastic Load Balancing (ELB) service that allows customers to insert third-party virtual appliances such as firewall, intrusion detection and prevention systems (IDS/IPS), network observability and others, transparently into the traffic path. Application Load Balancer (ALB) and Network Load Balancer (NLB) are reverse proxies and traffic is routed […]

Load Shedding Load shedding is the practice of sacrificing enough application traffic to keep partial availability in the presence of an overload condition. Used in conjunction with strategies like load balancing, load shedding helps applications support service level agreements (SLAs) when increased traffic overwhelms available system resources. While the cloud’s elasticity reduces the need for […]

Application Load Balancer (ALB) is a fully managed layer 7 load balancing service that load balances incoming traffic across multiple targets, such as Amazon EC2 instances. ALB supports advanced request routing features based on parameters like HTTP headers and methods, query string, host and path based routing. ALB also offloads important capabilities including TLS termination, […]

Update: On September 27th, 2021, we launched Application Load Balancer(ALB)-type target groups for Network Load Balancer (NLB). With this launch, you can register ALB as a target of NLB to forward traffic from NLB to ALB without needing to actively manage ALB IP address changes through Lambda. You can also use AWS Global Accelerator to […]

Introduction Network Load Balancer (NLB), part of the Elastic Load Balancing Family, is the flagship Layer 4 load balancer for AWS. It offers elastic capacity, high performance, and integration with many other AWS services (such as Amazon EC2 Auto Scaling). NLB is designed to handle millions of requests per second while maintaining ultra-low latency, improving […]

Introduction In this article, I will walk you through the steps to configure Amazon API Gateway in combination with AWS Global Accelerator to present Internet-facing API via static IP addresses to end users. This design addresses the need for static IP safelisting and also provides additional performance benefits to end users by sending user’s traffic […]

Introduction Internet-facing applications, by their nature, have a larger attack surface and are exposed to categories of threats most other types of applications will never have to face. Having the necessary protection from attacks on these types of applications, and minimizing the impact of attacks, are a core part of any security strategy. Traditional AWS […]

Updated “Cross-zone load balancing and appliance failures” section on 25th March, 2021 Organizations use next-generation firewalls (NGFW) and intrusion prevention systems (IPS) as part of their defense in depth strategy. In an on-premises network, these often take the form of dedicated hardware or software or virtual “appliances.” As companies move to the cloud, they want […]
