The AWS Well-Architected Framework enables customers to understand best practices around security, reliability, performance, and cost optimization when building systems on AWS. This approach helps customers make informed decisions and weigh the pros and cons of application design patterns for the cloud. In this session, you'll learn how National Instruments used the Well-Architected Framework to follow AWS guidelines and best practices. By developing a strategy based on the AWS Well-Architected Framework, National Instruments was able to triple the number of applications running in the cloud without additional head count, significantly increase the frequency of code deployments, and reduce deployment times from two weeks to a single day. As a result, National Instruments was able to deliver a more scalable, dynamic, and resilient LabVIEW platform with agility.

  2. 2. What to expect from the session What is the AWS well-architected framework? What are core tenets to being well architected? Customer use case: National Instruments getting to well architected
  3. 3. AWS Well-Architected Framework
  4. 4. AWS well-architected framework Stop guessing capacity needs Test systems at scale Data-driven architectures Automate to enable experimentation Allow for evolution General design principles to facilitate good design in the cloud
  5. 5. AWS well-architected framework Security Reliability Performance efficiency Cost optimization Set of questions you can use to evaluate how well an architecture is aligned to AWS best practices Operational excellence
  6. 6. Security pillar Security at all layers Enable traceability Implement a principle of least privilege Focus on securing system Automate security best practices Protect information, systems, and assets while delivering business value through risk assessments and mitigation strategies
  7. 7. Reliability pillar Test recovery procedures Automatically recover from failure Scale horizontally to increase availability Stop guessing capacity Ability of a system to recover from infrastructure or service disruptions, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfigurations or transient network issues
  8. 8. Performance efficiency pillar Democratize advanced technologies Go global in minutes Use server-less architectures Experiment more often Efficiently use of computing resources to meet requirements, and maintaining that efficiency as demand changes and technologies evolve
  9. 9. Cost optimization pillar Analyze and attribute expenditure Managed services to reduce TCO Adopt a consumption model Benefits from economies of scale Stop spending money on data center operations Assess your ability to avoid or eliminate unneeded costs or suboptimal resources, and use those savings on differentiated benefits for your business
  10. 10. Operational excellence pillar Perform operations with code Align operations processes to business objectives Make regular, small, incremental changes Test for responses to unexpected events Learn from operational events and failures Keep operations procedures current Operational practices and procedures used to manage production workloads
  11. 11. Well-architected framework example issues Security Reliability Managing keys and credentials – No MFA or rotation policy is in place Analyzing AWS-specific logs – Logs are not analyzed Encrypting and protecting data at rest – Data at rest encryption is not required Planning for recovery – Unplanned Seeking help with AWS infrastructure problems – Ad hoc System adapts to changes in workload – Ad hoc
  12. 12. Well-architected framework example issues Performance Cost optimization Storage solution matches demand – Reactive Evaluate new storage options – Ad hoc Evaluate new instance options – Ad hoc Meet demand cost effectively – Fixed amount of resources Govern AWS usage – No policies or mechanisms
  13. 13. National Instruments: Achieving Agility
  14. 14. NI equips engineers and scientists with systems that accelerate productivity, innovation, and discovery “Products used from toys to supercolliders” 40-year-old company headquartered in Austin, TX; annual sales greater than $1.25 B
