As part of adopting a multi-tenant SaaS model, a key challenge is how to provide strong tenant isolation in a cost effective and scalable manner. Being able to effectively isolate your tenants is an important part of a multi-tenant system. Learn how dynamic policy generation gets applied as part of the overall isolation story of your SaaS solution, and follow along with AWS reference implementation to demonstrate how to use dynamically generated policies in code.

Many companies are using Amazon Redshift to analyze and transform their data. As data continues to grow and become even more important, they are looking for more ways to extract valuable insights. One use case we’re especially excited to support is that of data tokenization and masking. Amazon Redshift has collaborated with Protegrity, an AWS Advanced Technology Partner, to enable organizations with strict security requirements to protect their data while being able to obtain the powerful insights.

Moving data between multiple data stores requires an extract, transform, load (ETL) process using various data analysis approaches. ETL operations form the backbone of any modern enterprise data and analytics platform. AWS provides a broad range of services to deploy enterprise-grade applications in the cloud. This post explores a strategic collaboration between Tech Mahindra and a customer to build and deploy an enterprise data repository on AWS and create ETL workflows using a serverless architecture.

It can be complicated to maintain a robust, scalable, and reliable monitoring system that inputs terabytes of data under heavy traffic. Learn how Thundra has delivered 99.9 percent availability to customers since incorporating AWS services into its product. Thundra’s platform can handle scalability and availability challenges, recover both from partial failures and major outages, and support point-in-time recovery in case of disaster.

When building a complex web service such as a serverless application, sooner or later you must deal with permission control. Amazon Cognito is a powerful authentication and authorization service managed by AWS and is often combined with Amazon API Gateway and AWS Lambda to build secure serverless web services. Through the blueprint of an AWS Lambda authorizer, learn how to implement object-based authorization in serverless applications on AWS.

There is a flurry of contact center solutions being brought to market, but enterprise customers often find these solutions time-consuming, cost-intensive, and difficult to implement. Learn how to integrate an Amazon Connect instance with Salesforce Service Cloud to automatically create a case in Salesforce using REST APIs and Amazon Kinesis Data Streams. This allows you to proactively handles call drops occurring for customers when they dial into a contact center solution.

Upgrading legacy systems to the cloud can seem daunting and time-consuming, but with the right combination of AWS Systems Manager, AWS Directory Service, and a few simple AWS Lambda functions, you can upgrade from your outdated Windows environments flawlessly, seamlessly, and at scale. Learn how you can run an in-place upgrade of your Windows 2008 R2 production instances to Windows 2019 R2, and how to control instance tagging so you can orchestrate the root volume replacement process.

Many SaaS organizations leverage AWS Identity and Access Management (IAM) to define a series of policies and roles that can be used to ensure tenants are not allowed to cross tenant boundaries when accessing resources. To make this work, you have to create separate policies for each tenant which can create an explosion of tenant policies that push the account limits of IAM. Learn how dynamic policy generation creates a more scalable and manageable isolation experience.

Many Windows solutions have used Microsoft SQL Server Integration Services (SSIS) as a method for performing ETL operations. Legacy SSIS packages that have been handed down to different developers over the years can be complex, cumbersome, and difficult to support. See an architecture and several techniques Cognizant uses to help clients with ETL operations based on legacy SSIS packaging move their applications to the AWS Cloud.

Providing a better experience at lower cost is the desired result of any organization and product. In most cases, it requires software re-architecting, planning, infrastructure configurations, benchmarking, and more. Epsagon provides a solution for monitoring and troubleshooting modern applications running on AWS. Dive deep on some of the best practices Epsagon has developed to improve the performance and reduce the cost of using serverless environments.
