1. Cloud

"The cloud" refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world.

1.1 Cloud Design Patterns

1.1.1 Data Management

#	Title	Summmary
1	Cache-Aside	Load data on demand into a cache from a data store
2	CQRS	Segregate operations that read data from operations that update data by using separate interfaces.
3	Event Sourcing	Use an append-only store to record the full series of events that describe actions taken on data in a domain.
4	Index Table	Create indexes over the fields in data stores that are frequently referenced by queries.
5	Materialized View	Generate prepopulated views over the data in one or more data stores when the data isn't ideally formatted for required query operations.
6	Sharding	Divide a data store into a set of horizontal partitions or shards.
7	Static Content Hosting	Deploy static content to a cloud-based storage service that can deliver them directly to the client.
8	Valet Key	Use a token or key that provides clients with restricted direct access to a specific resource or service.

1.1.2 Design and Implementation

#	Title	Summmary
1	Ambassador	Create helper services that send network requests on behalf of a consumer service or application.
2	Anti-Corruption Layer	Implement a façade or adapter layer between a modern application and a legacy system.
3	Backends for Frontends	Create separate backend services to be consumed by specific frontend applications or interfaces.
4	CQRS	Segregate operations that read data from operations that update data by using separate interfaces.
5	Compute Resource Consolidation	Consolidate multiple tasks or operations into a single computational unit
6	External Configuration Store	Move configuration information out of the application deployment package to a centralized location.
7	Gateway Aggregation	Use a gateway to aggregate multiple individual requests into a single request.
8	Gateway Offloading	Offload shared or specialized service functionality to a gateway proxy.
9	Gateway Routing	Route requests to multiple services using a single endpoint.
10	Leader Election	Coordinate the actions performed by a collection of collaborating task instances in a distributed application by electing one instance as the leader that assumes responsibility for managing the other instances.
11	Pipes and Filters	Break down a task that performs complex processing into a series of separate elements that can be reused.
12	Sidecar	Deploy components of an application into a separate process or container to provide isolation and encapsulation.
13	Static Content Hosting	Deploy static content to a cloud-based storage service that can deliver them directly to the client.
14	Strangler Fig	Incrementally migrate a legacy system by gradually replacing specific pieces of functionality with new applications and services.

1.1.3 Messaging

#	Title	Summmary
1	Asynchronous Request-Reply	Decouple backend processing from a frontend host, where backend processing needs to be asynchronous, but the frontend still needs a clear response.
2	Claim Check	Split a large message into a claim check and a payload to avoid overwhelming a message bus.
3	Choreography	Have each component of the system participate in the decision-making process about the workflow of a business transaction, instead of relying on a central point of control.
4	Competing Consumers	Enable multiple concurrent consumers to process messages received on the same messaging channel.
5	Pipes and Filters	Break down a task that performs complex processing into a series of separate elements that can be reused.
6	Priority Queue	Prioritize requests sent to services so that requests with a higher priority are received and processed more quickly than those with a lower priority.
7	Publisher-Subscriber	Enable an application to announce events to multiple interested consumers asynchronously, without coupling the senders to the receivers.
8	Queue-Based Load Leveling	Use a queue that acts as a buffer between a task and a service that it invokes in order to smooth intermittent heavy loads.
9	Scheduler Agent Supervisor	Coordinate a set of actions across a distributed set of services and other remote resources.
10	Sequential Convoy	Process a set of related messages in a defined order, without blocking processing of other groups of messages.

2. DDoS

In a distributed denial-of-service (DDoS) attack, a network of computers work in tandem to overflow an access point and prevent legitimate users from accessing a service.

3. Microservice

Microservices - also known as the microservice architecture - is an architectural style that structures an application as a collection of services that are

• Highly maintainable and testable
• Loosely coupled
• Independently deployable
• Organized around business capabilities
• Owned by a small team

The microservice architecture enables the rapid, frequent and reliable delivery of large, complex applications. It also enables an organization to evolve its technology stack.
