If your decentralized application (dApp) must interact directly with AWS services like Amazon S3 or Amazon API Gateway, you must authorize your users by granting them temporary AWS credentials. This solution uses Amazon Cognito in combination with your users’ digital wallet to obtain valid Amazon Cognito identities and temporary AWS credentials for your users. It […]

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 […]

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 […]

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. […]

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 […]

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 […]

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 […]

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 […]

Edge computing comprises elements of geography and networking and brings computing closer to the end users of the application. For example, using a content delivery network (CDN) such as AWS CloudFront can help video streaming providers reduce latency for distributing their material by taking advantage of caching at the edge. Another example might look like […]

Architecture diagrams visually communicate and document the high-level design of a solution. As the level of detail increases, so does the diagram’s size, density, and layout complexity. Using Sequence Diagrams, you can explore additional usage scenarios and enrich your understanding of the distributed architecture while continuing to communicate visually. This post takes a sample architecture […]
