Cloud computing telah menjadi pilihan popular bagi banyak organisasi kerana kelebihan fleksibiliti, kebolehcapaian, dan kecekapan kosnya. Jika ada lagi yang ingin anda tahu, jangan ragu untuk bertanya!
A server is a dedicated computer or device that provides services or resources to clients in a client-server model. It can handle functions like data sharing, computation, or resource management, often specializing in tasks such as hosting websites, data storage, or email management.
Linux administration involves managing systems through user management, monitoring, security configuration, software installation, network setup, file management, service control, automation, and troubleshooting, ensuring efficient and secure operation, especially on servers.
Emerging Technologies, including how IDC defines them and current investment trends in the field. He also discusses some of the technologies that could begin the next wave of innovation, and the challenges that could arise in their implementation.
Fiber-optic communication transmits data as light signals through glass or plastic fibers. Light pulses travel via internal reflection, and a receiver converts them back to electrical signals. It’s fast, with high bandwidth and minimal interference
A database is an organized collection of structured data that enables efficient storage, retrieval, and management. It is managed by a database management system (DBMS) and is used for various applications, such as storing customer information and inventory.
A network is a system of connected devices, like computers and servers, that share data and resources. It uses communication protocols to enable collaboration between devices. Networks can range from small local setups (LAN) to large global ones (WAN), like the internet.
Data communication transfers data electronically, enabling efficient information delivery and global collaboration. It supports flexibility, outsourcing, and faster decision-making within organizations. Integrated into core functions, it enhances productivity through e-mail, file transfers, and quicker product development.
A digital system processes data using binary code (0s and 1s) for calculations and operations. It enables efficient data handling in devices like computers and smartphones. These systems are crucial in computing, communication, and control technologies.
AWS (Amazon Web Services) is a cloud computing platform that offers a wide range of services, including computing power, storage, and databases, on a pay-as-you-go basis. It helps businesses scale, store data, and run applications without managing physical servers. AWS supports global infrastructure for web hosting, AI, analytics, and more.
OpenStack is a collection of software modules, called projects, that work together to create and manage cloud infrastructures. Installing OpenStack on top of a virtualized environment forms a cloud operating system and broadens the pool of computing resources available for things like application hosting or big data tasks.
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that offers resizable compute capacity in the cloud. It enables users to launch and manage virtual servers, called instances, for running applications and hosting websites. EC2 instances can be customized with various CPU, memory, and storage options to suit different workload needs.
Cloud Architecture involves the structure of cloud services, including models like IaaS (infrastructure), PaaS (platform), and SaaS (software). It also includes deployment types: public cloud (shared resources), private cloud (dedicated resources), and hybrid cloud (a mix of both). These define how cloud services are organized and delivered.
Virtualization enables the creation of virtual machines (VMs) and storage, allowing multiple VMs to run on one physical system. It efficiently manages resources like CPU, memory, and storage in cloud environments. Virtualization enhances scalability, flexibility, and cost-effectiveness by optimizing hardware usage.
Cloud Security focuses on protecting data, applications, and infrastructure in cloud environments. It ensures data protection through encryption, access controls, and monitoring. Cloud security also addresses privacy and compliance with regulations like GDPR and HIPAA, safeguarding sensitive information and ensuring legal adherence.
Cloud Storage involves managing scalable storage resources that can grow with demand, including object storage, block storage, and databases. It allows users to store and access data remotely over the internet. Cloud storage is highly flexible, offering automated backups, redundancy, and easy data retrieval from anywhere.
You will come to know about the advent of DevOps, different stages in DevOps and what all tools are needed in those stages. You will understand the relationship between the Development team and the Operations team in the DevOps process. Later in the video you shall understand the applicability of DevOps and some tech giants that work on the DevOps culture.
Cloud computing allows online data storage and access without physical servers, enabling remote work. In contrast, blockchain technology (Distributed Ledger Technology) stores data in timestamped blocks, creating a decentralized and secure system. Both technologies offer unique benefits that revolutionize modern IT operations.
Software as a Service (SaaS) provides software applications online via subscription, allowing access through a web browser (e.g., Google Workspace). Platform as a Service (PaaS) enables developers to build and manage applications without infrastructure concerns (e.g., Google App Engine). Infrastructure as a Service (IaaS) offers virtualized computing resources, allowing control over OS and applications without managing physical hardware (e.g., Amazon Web Services).
There are many kinds of backup techniques, but the three primary types of data backup include full backups, differential backups, and incremental backups. A full backup is quite self-explanatory -- it’s when an entire data set is backed up at once, either to the cloud, magnetic tapes, HDD, or other form of storage.
