 # DB Instances
 
-The term "DB Instance" is used within the context of Amazon's Relational Database Service (RDS). A DB Instance is essentially an isolated database environment in the cloud, run within Amazon RDS. A DB Instance can contain multiple user-created databases, and can be accessed using the same tools and applications that you might use with a stand-alone database instance. You can create and manage a DB Instance via the AWS Management Console, the AWS RDS Command Line Interface, or through simple API calls.

Moreover, General Purpose SSD (gp2) volumes also provide the ability to burst to higher levels of performance when needed.

 # Provisioned IOPS
 
 "Provisioned IOPS" is a storage option available in Amazon Web Services' (AWS) Elastic Block Store (EBS). This option is designed to deliver fast, predictable, and consistent I/O performance. It allows you to specify an IOPS rate when creating a volume, and AWS will provision that rate of performance, hence the name. It's primarily suitable for databases and workloads that require high IOPS. An EBS volume with provisioned IOPS is backed by solid-state drives (SSDs), and you can specify up to a maximum of 64,000 IOPS per volume.

 # Backup / Restore
 
-`Backup Restore` in AWS RDS provides the ability to restore your DB instance to a specific point in time. When you initiate a point-in-time restore, a new DB instance is created and all transactions that occurred after the specified point-in-time are not part of the new DB instance. You can restore up to the last restorable time (typically within the last five minutes) as indicated in the AWS RDS Management Console. The time it takes to create the restore depends on the difference in time between when you initiate the restore and the time you are restoring to. The process happens with no impact on the source database and you can continue using your database during restore.

-In Amazon DynamoDB, tables are a collection of items. An item is a group of attributes that is identified by a primary key. Items are similar to rows or records in other database systems. Each item in a table is uniquely identifiable by a primary key. This key can be simple (partition key only) or composite (partition key and sort key). Every attribute in an item is a name-value pair. The name of the attribute is a string and the value of an attribute can be of the following types: String, Number, Binary, Boolean, Null, List, Map, String Set, Number Set, and Binary Set.

-DynamoDB supports two types of primary keys, namely `Partition Key` and `Composite Key` (Partition Key and Sort Key). A `Partition Key`, also known as a hash key, is a simple primary key that has a scalar value (a string, a number, or a binary blob). DynamoDB uses the partition key's value to distribute data across multiple partitions for scalable performance. A `Composite Key` consists of two attributes. The first attribute is the partition key, and the second attribute is the sort key. DynamoDB uses the partition key to spread data across partitions and also uses the sort key to store items in sorted order within those partitions. This sort key provides further granular control over data organization.

 # Data Modeling
 
 In AWS DynamoDB, data modeling is a process that involves determining how to organize, access, and understand the data stored in a database. This process is crucial as it outlines how data will be stored and accessed across a wide range of databases and applications. The primary components of data modeling in DynamoDB include tables, items, and attributes. Tables are collections of data. Items are individual pieces of data that are stored in a table. Attributes are elements of data that relate to a particular item. DynamoDB uses a NoSQL model which means it’s schema-less, i.e., the data can be structured in any way that your business needs  
-prescribe, and can be changed at any time. This contrasts with traditional relational databases which require pre-defined schemas.

 # Streams
 
-AWS DynamoDB Streams is a time-ordered sequence of item-level modifications in any DynamoDB table. When you enable a stream on a table, DynamoDB captures information about every modification to data items in the table. The changes are recorded in near real-time and can be set up to trigger AWS Lambda functions immediately after an event has occurred. With DynamoDB Streams, applications can access this log and view the data modifications in the order they occurred. The stream records item-level data modifications such as `Insert`, `Modify`, and `Remove`. Each stream record is then organized into a stream view type, where applications can access up to 24 hours of data modification history.

 # Limits
 
-In terms of DynamoDB, it’s important to be aware of certain limits. There are two types of capacity modes - provisioned and on-demand, with varying read/write capacity units. You have control over the provisioning of throughput for read/write operations. However, there's a maximum limit of 40000 read capacity units and 40000 write capacity units for on-demand mode per table. It's also important to note that the partition key value and sort key value can be a maximum of 2048 bytes and 1024 bytes respectively. Each item, including primary key, can be a maximum of 400KB. The total provisioned throughput for all tables and global secondary indexes in a region cannot exceed 20,000 write capacity units and 20000 read capacity units for on-demand mode. Remember, you can request to increase these limits by reaching out to AWS Support.

ECS eliminates the need for you to install, operate, and scale your own cluster management infrastructure.

 # Creating / Invoking Functions
 
-To create a Lambda function in AWS, navigate to the AWS Management Console, select "Lambda" under "Compute" and then "Create function". Specify the function name, execution role and runtime environment. Once the function is created, you can write or paste the code into the inline editor. To invoke a Lambda function, you can either do it manually, via an API gateway, or schedule it. Manually invoking can be done by selecting your function in the AWS console, then "Test", add the event JSON and "Test" again. If set up with an API gateway, it'll be triggered when the endpoints are hit. Scheduling involves using AWS Cloudwatch to trigger the functions periodically.

 # Layers
 
-AWS Lambda layers are distribution mechanisms for libraries, custom runtimes, and other function dependencies. In other words, they are a distribution mechanism for artifacts. The layers can be versioned, and each version is immutable. An AWS Lambda layer is a ZIP archive that contains libraries, a custom runtime, or other dependencies. Lambda functions can be configured to reference these layers. The layer is then extracted to the `/opt` directory in the function execution environment. Each runtime looks for libraries in a different location under the `/opt` folder, depending on the language.

 # Custom Runtimes
 
-AWS Lambda supports several preconfigured runtimes for you to choose from, including Node.js, Java, Ruby, Python, and Go. However, if your preferred programming language or specific language version isn't supported natively, you can use **custom runtimes**. A custom runtime in AWS Lambda is a Linux executable that handles invocations and communicates with the Lambda service. It enables you to use any programming language to handle AWS Lambda events. The runtime is responsible for running the bootstrap, which is an executable file, to start the execution process environment, process incoming requests, and manage interaction between your function code and the infrastructure.

 # Versioning / Aliases
 
-In AWS Lambda, **Versioning** provides a way to manage distinct and separate iterations of a Lambda function, enabling both risk reduction and more efficient development cycles. Conversely, an **Alias** is a pointer to a specific Lambda function version. Aliases are mutable; they can be re-associated to a different version, manifesting a form of flexibility. With aliases, one can avoid direct updating of event triggers or downstream services as they can point to an alias and the corresponding version can be updated, hence separating the infrastructure/code changes.

 # Cold Start and Limitations
 
-AWS Lambda's cold start refers to the delay experienced when Lambda invokes a function for the first time or after it has updated its code or dependencies. This happens because Lambda needs to do some initial setup, such as initializing the runtime, before it can execute the function code. This setup process adds to the function's execution time, and is particularly noticeable in situations where low latency is critical. Cold start times also vary based on the memory size, with bigger lambda functions taking longer times to start. Further, unused functions may face a cold start again as AWS may clear out idle resources from time to time.
