Data that provides information about other data, commonly used for tagging, categorization, and management.

Microservices

An architectural approach that structures applications as a collection of loosely coupled, independently deployable services.

Migration

The process of moving applications, data, or infrastructure from one environment to another, often to the cloud.

Mirror

Creating an exact copy of data or systems for backup, redundancy, or load distribution purposes.

MLOps

The practice of applying DevOps principles to machine learning workflows, including model development, deployment, and monitoring.

Monitoring

The continuous observation of systems, applications, and infrastructure to detect issues and ensure optimal performance.

Multi-AZ (Multi-Availability Zone)

A deployment strategy that distributes resources across multiple availability zones for high availability and fault tolerance.

Multi-Cloud

A cloud computing strategy that uses services from multiple cloud providers to avoid vendor lock-in and optimize capabilities.

A security process that requires users to provide multiple forms of verification before accessing systems or data.

Multi-Region

A deployment architecture that spans multiple geographic regions to improve performance, availability, and disaster recovery.

Multi-Tenant

An architecture where multiple customers (tenants) share the same application instance while maintaining data isolation.

MySQL

An open-source relational database management system widely used for web applications and cloud services.

Maintenance Window

A scheduled time period when systems undergo updates, patches, or maintenance activities that may cause downtime.

Message Broker

A software component that facilitates communication between applications by translating messages between different protocols.

Message Passing

A communication method where processes exchange information by sending and receiving messages rather than sharing memory.

Mesh Network

A network topology where each node connects to multiple other nodes, providing redundant paths and improved reliability.

Middleware

Software that acts as a bridge between different applications, operating systems, or database systems.

Model Training

The process of teaching a machine learning algorithm to make predictions by feeding it training data.

MongoDB

A popular NoSQL document database that stores data in flexible, JSON-like documents.

Mount Point

A directory in a file system where additional storage devices or file systems are attached and made accessible.

Amazon's fully managed service for Apache Kafka that makes it easy to build and run applications that use Kafka.

MQTT (Message Queuing Telemetry Transport)

A lightweight messaging protocol designed for small sensors and mobile devices optimized for high-latency networks.

Machine Image

A template containing a software configuration including an operating system, application server, and applications.

Managed Identity

A feature that provides Azure services with an automatically managed identity for authenticating to other Azure services.

Management Console

A web-based interface for managing cloud resources, services, and configurations through a graphical user interface.

Maximum Transmission Unit (MTU)

The largest size packet or frame that can be sent in a packet-switched network without fragmentation.

Memory Optimization

Techniques and configurations to efficiently use system memory and improve application performance.

Message Delivery

The process of transmitting messages from senders to receivers, including delivery guarantees and ordering.
