Other Infrastructure - 3.1
On-Premises
IT staff manage infrastructure on-site, providing full control and ownership over hardware and software systems.
Centralized vs. Decentralized
In decentralized setups, resources are distributed across multiple locations, using different providers, operating systems, and infrastructure. This increases complexity in management compared to centralized systems, where monitoring, logs, and data are collected in a single location, simplifying management and providing more comprehensive visibility.
Virtualization
Virtualization allows multiple virtual machines (VMs) to run on a single physical server, each acting as an independent system. This improves resource utilization and scalability.
Containerization
Containers package the application code along with its dependencies, libraries, and settings into an isolated unit. Containers are more lightweight compared to virtual machines and are ideal for consistent application deployment across different environments.
IoT - Internet of Things
IoT refers to connecting everyday devices to the internet, allowing for remote monitoring and control. However, IoT devices often lack robust security measures, leading to vulnerabilities, especially due to the difficulty in applying updates and patches to large numbers of distributed devices.
SCADA - Supervisory Control and Data Acquisition Systems
SCADA systems are used in industrial environments to monitor and control infrastructure like power grids, water treatment plants, and manufacturing systems. These systems are crucial for critical infrastructure and must be protected from cyberattacks.
Real-Time Operating System - RTOS
A Real-Time Operating System is designed to process data as it comes in, typically in embedded systems, ensuring tasks are completed within strict timing constraints. RTOS is used in critical applications where delays could lead to system failure or safety concerns, such as in medical devices, automotive systems, or aerospace.
Embedded Systems
Embedded systems are computers designed for specific tasks, integrated within larger systems. They are commonly found in devices such as medical equipment, automobiles, and household appliances.
High Availability - HA
High Availability (HA) refers to designing systems to ensure they remain operational with minimal downtime. This is achieved by using failover mechanisms, load balancing, and redundant components to allow systems to continue functioning in the event of hardware or software failure.
