Cloud Computing Architecture: Computer Science

LECTURE NOTES CLOUD COMPUTING ARCHITECTURE Cloud computing and cloud storage are becoming interesting topics for addressing common IT problems and challenges as well as presenting new opportunities. For some environments, the primary goal is to cut costs, while for others it is to support growth. In addition, som environments need to improve service level objectives (SLOs) as well as meet service level agreements (SLAs) for availability, performance, security, and data protection. Common challenges that cloud solutions address include :  Scalability - Cloud solutions provide on-demand scalability to meet changing needs.  Cost Efficiency - Cloud solutions provide cost-efficient access to computing resources.  Accessibility - Cloud solutions make it easy to access your resources from anywhere with an internet connection.  Security - Cloud solutions offer robust security features and centralized management of security controls.  Disaster Recovery - Cloud solutions provide reliable backup and disaster recovery options.  Compliance - Cloud solutions offer compliance features and help organizations meet regulatory requirements. The essence of conventional IT, hosting, managed service provider (MSP), and cloud can be summarized as follows :  Conventional IT - Traditional approach to managing and maintaining IT systems inhouse.  Hosting - Practice of hosting applications or services on a third-party server.  Managed Service Provider (MSP) - A third party that manages and maintains the customer's IT systems.  Cloud - Practice of accessing computing resources over the internet on a pay-as-you-go basis. Network and storage technologies are essential components of cloud computing and cloud storage systems, as they help to meet a variety of requirements, such as: 1. Scalability - Network and storage technologies enable easy scaling to accommodate changing demands. 2. Accessibility - Network technologies provide access to cloud storage systems from anywhere with an internet connection. 3. Redundancy - Network and storage technologies can provide redundancy to ensure data is not lost in the event of failures. 4. Performance - Network technologies can optimize performance and reliability of cloud storage systems. 5. Security - Network and storage technologies can implement security measures to protect data from unauthorized access. 6. Cost-Effectiveness - Network and storage technologies help reduce costs by optimizing resource utilization and reducing physical infrastructure needs. Cloud computing architecture refers to the design and structure of a cloud computing system. Here are the main components of cloud computing architecture :  Frontend - The user interface through which users access cloud services.  Backend - The infrastructure that stores and processes data.  Cloud Service Delivery Models - Models defining how cloud services are delivered to users (SaaS, PaaS, IaaS).  Cloud Deployment Models - Models defining how the cloud infrastructure is deployed and managed (public, private, hybrid, community clouds).  Cloud Management Platform - Used to manage and monitor the cloud infrastructure.  Cloud Network - The communication infrastructure that connects different cloud components and enables data transfer. Seagate offers a range of solutions for cloud computing, including:  Cloud Storage - Seagate offers cloud storage solutions for secure data storage, access, and sharing over the internet.  High-Capacity Hard Drives - Seagate's hard drives are designed for use in cloud storage systems, providing reliable and cost-effective storage.  Solid-State Drives (SSDs) - Seagate's SSDs provide high-performance for cloud computing applications, with fast read/write speeds and low latency.  Data Recovery Services - Seagate offers data recovery services for cloud storage systems to help organizations recover from disasters or failures.  Security - Seagate provides security solutions, including self-encrypting drives and secure erase functionality, to protect data from unauthorized access.  Management Software - Seagate's management software allows for easy monitoring and management of cloud storage systems, optimizing performance and reliability.
