Top migration challenges we hear from customers “We see challenges with existing software contracts, license portability, and vendor willingness to price reasonably during the move of dozens/hundreds of vendors” “We want to evaluate and onboard new software vendors during migration” “We want to bring on-premises governance controls to cloud apps” “We need to drive culture change beyond IT as we transform our businesses to digital and from on-premises to cloud” © 2020, Amazon Web Services, Inc. or its Affiliates.

Consider how you integrate applications & modular services Synchronous: API-based Asynchronous: event-driven Inter/intra-service Common for communication between apps Common for communication within apps Scalability Tools required to manage point-to-point connections Nearly infinitely scalable Cost Provisioning for peak use leads to low CPU utilization Scales to 0—cost benefits of “pay for use” Latency Can be very low Higher in theory—but latency requirements are rarely as low as you think (think about P50, P99, etc.) Agility Easy to get started; hard to use point-to-point in large scale Decoupled systems increase agility dramatically © 2020, Amazon Web Services, Inc. or its Affiliates.

General Best Practices • Clearly define an AWS account-creation process. • Define a company-wide AWS usage policy • Create a security account structure for managing multiple accounts. • Leverage AWS APIs and scripts. © 2020, Amazon Web Services, Inc. or its Affiliates.

IAM General Best Practices • • • • • • • • • • • • Lock away your AWS account (root) access keys Create individual IAM users Use groups to assign permissions to IAM users Grant least privilege Configure a strong password policy for your users Enable MFA for privileged users Use roles for applications that run on Amazon EC2 instances Delegate by using roles instead of by sharing credentials Rotate credentials regularly Remove unnecessary credentials Use policy conditions for extra security Monitor activity in your AWS account © 2020, Amazon Web Services, Inc. or its Affiliates.

SLIs, SLOs, and SLAs
SLIs A Service Level Indicator is a quantitative measurement that expresses an aspect of the service (commonly a metric).
SLOs A Service Level Objective is a target value for a service, as measured via an SLI.
SLAs A Service Level Agreement is a contract that defines the results (and consequences) of meeting (or missing) one or more SLOs.

Data-driven decision making Good data helps you make good decisions by lowering cognitive load, empowering teams to be independent, and unlocking creativity and potential.
Security Posture Management
Security Posture Management Assess and visualize the current and historic security posture of your cloud environment, automate audit evidence collection, and catch configuration issues.
Security Signals Security Signals are generated using Detection Rules. Detection Rules detect threats across different sources and are available out of the box for immediate use.
Demo
You’re starting to realise the benefits of a modern cloud migration—but you’ve only started to unlock the full potential of your organisation. Now it’s time to bring everybody else on board, and that takes more than just technology decisions.
In part three of this three-part joint AWS and Datadog webinar series, we’ll explore the relationships between team and organisational structures in a modern, cloud-native environment, and how to use high-quality signals to encourage communication and build trust across business units.
Starting with the cloud-native scenario presented in part two, we’ll introduce organisational models for both data and personnel, with a concentration on DevOps principles and the power of data-driven decision making. As always, good observability practices are key, as you need the best data to identify your key signals and build your service level indicators and objectives. Focusing on practitioners, we’ll demonstrate how to move beyond monitoring your systems, and leverage Datadog to add real business value.
