Load Balancing

Load Balancing distributes network traffic evenly across multiple servers or resources to optimize performance, enhance scalability, and prevent overload. In cloud computing, load balancers help distribute incoming requests across multiple instances or resources, ensuring efficient resource utilization and improved end-user responsiveness. Load balancing improves system availability and prevents bottlenecks in cloud-based applications.

Microservices

Microservices is an architectural approach in which applications are built as a collection of small, loosely coupled, and independently deployable services. Each service focuses on a specific business function and can be developed, deployed, and scaled independently. Microservices architecture promotes modularity, flexibility, and easier maintenance and enables organizations to build complex applications using a combination of services.

NoSQL

NoSQL, or "not only SQL," is a non-relational database management system that provides a flexible data model for storing and retrieving large volumes of unstructured and semi-structured data. NoSQL databases are highly scalable, distributed, and designed to handle the velocity, variety, and volume of data generated in cloud computing and big data environments. They offer high performance, horizontal scalability, and schema flexibility.

Orchestration

Orchestration is the automated management and coordination of multiple tasks, resources, and processes to achieve a desired outcome. In cloud computing, orchestration platforms enable the automation of complex workflows, provisioning, and management of resources, and deployment of applications. Orchestration tools help streamline and optimize cloud operations, reducing manual effort and ensuring consistency and efficiency.

PaaS (Platform as a Service)

PaaS, or Platform as a Service, is a cloud computing model that provides developers with a complete platform for developing, deploying, and managing applications without the complexity of infrastructure management. PaaS offerings include development tools, runtime environments, and pre-configured components, enabling developers to focus on application development rather than infrastructure setup. PaaS platforms provide scalability, flexibility, and cost-efficiency.

Replication

Replication is creating and maintaining copies of data across multiple locations or storage systems to ensure data availability, reliability, and fault tolerance. In cloud computing, data replication is a key mechanism for data backup, disaster recovery, and high availability. Depending on the specific requirements and objectives, replication techniques include synchronous replication, asynchronous replication, and multi-site replication.

Scalability 

Scalability is the ability of a system, application, or infrastructure to handle increasing workloads and accommodate growth without significant performance degradation. In cloud computing, scalability is critical as it allows organizations to expand or shrink their computing resources based on demand. Horizontal scalability involves adding more instances or nodes to distribute the workload, while vertical scalability involves increasing existing cases' help. Cloud platforms provide scalability through features like auto-scaling and load balancing.

SaaS (Software as a Service)

SaaS, or Software as a Service, is a cloud computing model providing software applications to users over the Internet. Instead of installing and maintaining software locally, users access applications through a web browser or API. SaaS eliminates the need for upfront infrastructure costs and software maintenance, as the cloud provider handles infrastructure management and software updates. Common examples of SaaS include email services, customer relationship management (CRM) tools, and project management platforms.
