• Edge location:  A site that CloudFront uses to cache copies of your content for faster delivery to users at any location.
• Elasticity:  The ability to acquire resources as you need them and release resources when you no longer need them. In the cloud, you want to do this automatically.
• Enhanced Networking:  Enhanced networking uses single root I/O virtualization (SR-IOV) to provide high-performance networking capabilities on supported instance types.
• Event:  An instance of something happening that is significant to the workload.
• Federated Identity:  Federated identities are those which enable users to have a single identity stored in an organizations central identity provider.
• Feedback loop:  A mechanism by which output from a process or system is fed back into the control of that process or system.
• Five whys:  Helps in identifying the root cause of a problem by determining the relationship between different root causes of a problem.
• Game day:  Simulates a failure or event to test systems, processes, and teams responses
• Horizontal scaling:  The ability for a system to grow by adding additional computers.
• IAM Policy:  Access in AWS is managed through policies, that can be attached to IAM identities or AWS resources.
• In-memory:  The state of being stored in volatile system RAM rather than on stable storage, such as flash or disk.
• Incident:  An event that requires an intervention or response.
• Indexes:  A technology that is designed to make looking up information more efficient.
• Ishikawa diagram:  Helps in capturing the causal relationship between cause and effect, and groups causes into meaningful groupings.
• Key distribution:  The relative probability that a given key to access data is spread out across storage.
• Latency:  A measurement of the amount of time between an action and the result, often between a request and a response.
• Latency-based Routing:  Improves performance by routing your customers to the AWS endpoint (e.g. EC2 instances, Elastic IPs or ELBs) that provides the fastest experience based on actual performance measurements of the different AWS regions where your application is running.
• Mechanical Sympathy:  Using a tool or system with an understanding of how it operates best.
• Memory:  A component of a computer system that is designed for short-term, fast-access, data storage; often this is Random-Access Memory (RAM), but there are other forms as well.
• Milestone:  Mark key changes in your architecture as it evolves.
• Multi-factor Authentication:  Multi-factor Authentication adds an extra layer of protection on top of your user name and password.
• Network address utilization:  This is a measurement of the percentage of non-overlapping address space you consume out of all private address spaces available. VPCs are restricted to 65535 addresses, and data centers and offices have defined ranges. Networks are defined by Classless Inter-Domain Routing (CIDR) ranges that cannot overlap.
• NoSQL:  NoSQL databases are purpose built for specific data models and have flexible schemas for building modern applications.
• Partition:  A division of elements, oftentimes data or resources, along certain boundaries.
• Partition tolerance:  A system's ability to continue to operate correctly when it has been partial separated; often in reference to a distributed system.
• Placement Group:  You can launch or start instances in a placement group, which determines how instances are placed on underlying hardware.
• Playbook:  A documented process to investigate the source of an issue.
• Principal engineering community:  Amazon's Principal Engineer Community sets the standard for engineering excellence at Amazon.

• Query capability:  A way to ask for information from a system.
• Relational database:  A relational database is a collection of data items with pre-defined relationships between them.
• Reliability:  The ability of a workload to perform its intended function correctly and consistently when it’s expected to. This includes the ability to operate and test the workload through its total lifecycle.
• Resiliency:  The ability of a workload to recover from infrastructure or service disruptions, dynamically acquire computing resources to meet demand, and mitigate disruptions, such as misconfigurations or transient network issues.
• Root User:  When you first create an Amazon Web Services (AWS) account, you begin with a single sign-in identity that has complete access to all AWS services and resources in the account. This identity is called the AWS account root user and is accessed by signing in with the email address and password that you used to create the account.
• Root cause analysis:  Helps in identifying what, how, and why an event or failure happened resulting in corrective and preventive measure.
• Runbook:  A procedure to achieve a specific outcome.
• Scalability:  A measurement of a system's ability to grow to accommodate an increase in demand.
• Service Limits:  Services have limitations to protect the consumer as well as the provider; physical locations have limitations built into their construction.
• Service accessibility:  Ensures consumers of the workload are able to access your services, either through the internet, private networking, or VPN.
• Solid-state drive:  Solid-state drives are a storage device that uses memory to store data.
• Storage optimization:  Choosing storage technology best matches the access patterns of the system using it.
• Tagging:  Assign metadata to AWS resources to categorize and organize.
• Technology portfolio:  The collection of workloads that are required for the business to operate.
• VPC Endpoint:  A VPC endpoint enables you to privately connect your VPC to supported AWS services and VPC endpoint services powered by PrivateLink without requiring an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. Instances in your VPC do not require public IP addresses to communicate with resources in the service. Traffic between your VPC and the other service does not leave the Amazon network.
• VPC Flow Logs:  enables you to capture information about the IP traffic going to and from network interfaces in your VPC.
• Workload:  The set of components that together deliver business value.
• network ACL:  An optional layer of security that acts as a firewall for controlling traffic in and out of a subnet. You can associate multiple subnets with a single network ACL, but a subnet can be associated with only one network ACL at a time.
