Unified API architecture

How Sonar built a unified API on AWS

SonarCloud, a software-as-a-service (SaaS) product developed by Sonar, seamlessly integrates into developers’ CI/CD workflows to increase code quality and identify vulnerabilities. Over the last few months, Sonar’s cloud engineers have worked on modernizing SonarCloud to increase the lead time to production. Following Domain Driven Design principles, Sonar split the application into multiple business domains, each […]

Example of a stateless architecture

Converting stateful application to stateless using AWS services

Designing a system to be either stateful or stateless is an important choice with tradeoffs regarding its performance and scalability. In a stateful system, data from one session is carried over to the next. A stateless system doesn’t preserve data between sessions and depends on external entities such as databases or cache to manage state. […]

Oracle with cascading standby databases across regions

Disaster Recovery for Oracle Database on Amazon EC2 with Fast-Start Failover

High availability is non-negotiable for organizations today to prevent business-critical application disruptions. Enterprises must prioritize database scalability and availability to avoid downtime in their databases, network, servers, or storage environments. For organizations that want to avoid required application changes, Oracle Real Application Clusters (RAC) is an option for providing high availability and scalability to the […]

Enable transparent connectivity to Oracle Data Guard environments using Amazon Route 53 CNAME records

Customers choose AWS for running their Oracle database workload to help increase resiliency, performance, and scalability of the database layer. A high availability (HA) solution for the database stack is an important aspect to consider when migrating or deploying Oracle databases in AWS to help ensure that the architecture can meet the service level agreement […]

Razorpay Edge request flow for DDoS handling

Mitigating DDoS with data science using AWS Shield Advanced and AWS WAF

This blog post helps customers in mitigating distributed denial-of-service (DDoS) using AWS Shield Advanced, AWS WAF, and data science. We explore how to use these services along with machine learning (ML) to detect and mitigate DDoS attacks. Bad actors conduct DDoS attacks using botnets. Through botnets, attackers look for zero-day vulnerabilities—specifically on network devices such […]

Warm standby with managed services

Disaster Recovery Solutions with AWS managed services, Part 3: Multi-Site Active/Passive

Welcome to the third post of a multi-part series that addresses disaster recovery (DR) strategies with the use of AWS-managed services to align with customer requirements of performance, cost, and compliance. In part two of this series, we introduced a DR concept that utilizes managed services through a backup and restore strategy with multiple Regions. […]

Building an event-driven solution for AvalonBay property leasing and search

In this blog post, we show you how to build an event-driven and serverless solution for property leasing and search that is scalable and resilient. This solution was created for AvalonBay Communities, Inc.—a leading residential Real Estate Investment Trusts (REITs). It enables: More than 150,000 multi-parameter searches per day The processing of more than 3,500 […]

Using a single DNS and Amazon Route 53 to route requests

Setup a high availability design for Oracle Data Guard (Fast-Start Failover) using Amazon Route 53

Many customers use Oracle Database deployed on Amazon Elastic Compute Cloud (Amazon EC2) to run their Oracle E-Business Suite applications. They rely on Oracle Data Guard for high availability databases, with a standby database running in a different availability zone. Oracle Data Guard can switch a standby database to the primary role in case a […]

Dimensions for operational visibility

A multi-dimensional approach helps you proactively prepare for failures, Part 3: Operations and process resiliency

In Part 1 and Part 2 of this series, we discussed how to build application layer and infrastructure layer resiliency. In Part 3, we explore how to develop resilient applications, and the need to test and break our operational processes and run books. Processes are needed to capture baseline metrics and boundary conditions. Detecting deviations […]

AWS managed services help in building resilient infrastructures (click the image to enlarge)

A multi-dimensional approach helps you proactively prepare for failures, Part 2: Infrastructure layer

Distributed applications resiliency is a cumulative resiliency of applications, infrastructure, and operational processes. Part 1 of this series explored application layer resiliency. In Part 2, we discuss how using Amazon Web Services (AWS) managed services, redundancy, high availability, and infrastructure failover patterns based on recovery time and point objectives (RTO and RPO, respectively) can help in […]
