Network address translation (NAT) in DNS refers to the process of translating IP addresses between different networks. It allows multiple devices within a local network to share a single public IP address. When a device from the local network communicates with external servers or devices over the internet, NAT dynamically assigns a unique port number … Read more
Powerline networks utilize the existing electrical wiring in buildings to transmit data signals. Devices called powerline adapters plug into standard electrical outlets, converting data from Ethernet cables into signals that can travel through the electrical wiring. Other powerline adapters elsewhere in the building receive these signals and convert them back into Ethernet data, allowing devices … Read more
The cloud native method focuses on developing applications specifically for cloud environments, utilizing microservices architecture and containerization. This method emphasizes scalability, resilience, and flexibility, leveraging cloud-native technologies to optimize performance and resource utilization. The cloud native approach involves building and running applications that utilize cloud computing principles, such as containerization, orchestration, and automation. It aims … Read more
An API gateway serves as an intermediary between clients (such as web or mobile applications) and backend services (microservices, databases, or other APIs). It acts as a single entry point for all client requests, handling various tasks to simplify and streamline the communication between clients and services. Here’s how it generally works: Request Handling: When … Read more
VLAN stands for Virtual Local Area Network, and its primary benefit lies in its ability to logically segment a single physical network into multiple virtual networks. This segmentation enhances network efficiency, security, and manageability by grouping devices into separate broadcast domains, even if they are physically connected to the same network infrastructure. VLANs allow administrators … Read more
Wireshark’s main function is to capture and analyze network packets flowing through a network interface. It allows network administrators, security professionals, and developers to inspect the details of network traffic in real-time or from captured packet data. Wireshark provides a powerful toolset for diagnosing network issues, monitoring network performance, troubleshooting security incidents, and debugging network … Read more
The 4 R’s of cloud migration refer to strategies organizations use to decide how to migrate their applications and workloads to the cloud: Rehost (lift and shift): Involves migrating applications from on-premises to the cloud with minimal changes to the architecture. It’s often quicker but may not fully leverage cloud benefits. Refactor (rearchitect): Involves redesigning … Read more
Packet loss, in networking, can occur due to various factors. One common cause is network congestion, where data packets are delayed or dropped because network devices such as routers and switches are overwhelmed with traffic. Another cause is network hardware issues, including faulty cables, malfunctioning network interface cards (NICs), or improperly configured equipment. Additionally, packet … Read more
The process of cloud migration involves several key steps to ensure a smooth transition of applications, data, and workloads from on-premises environments to cloud platforms. It typically includes: Assessment and Planning: Evaluating current IT infrastructure, applications, and dependencies to determine migration readiness. This step involves setting objectives, defining scope, identifying critical applications, and assessing risks. … Read more
The cloud migration process involves transferring an organization’s digital assets, such as applications, data, and IT processes, from on-premises infrastructure to a cloud environment. It typically begins with assessment and planning, where current systems are evaluated for cloud suitability and a migration strategy is developed. Following this, preparation involves optimizing applications and data for migration, … Read more
