Direct connect , A dedicated, private network connection between an on-premises data center and a cloud provider that bypasses the public internet for better stability., VPN, A secure, encrypted tunnel that allows users to send and receive data over a public network as if their devices were directly connected to a private network., common access types, The various methods used to connect to cloud resources, typically including public internet, private peering (Direct Connect), and secure tunnels (VPN)., RDP, A proprietary protocol developed by Microsoft that provides a user with a graphical interface to connect to another computer over a network., SSH, A cryptographic network protocol used for secure command-line access and remote administration of Linux or Unix-based systems., HTTPS, An extension of HTTP used for secure communication over a computer network by encrypting data with SSL/TLS., SDN, A networking architecture that uses software-based controllers to manage and direct network traffic rather than relying on physical hardware configurations., Load balancing , The process of distributing incoming network traffic across a group of backend servers to ensure no single server becomes overwhelmed., DNS, The phonebook of the internet that translates human-readable domain names (like https://www.google.com/search?q=google.com) into machine-readable IP addresses., firewall, A security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules., Compression , A technique that reduces the size of data files by removing redundancies, allowing for more efficient use of storage space., deduplication, A specialized data compression technique that eliminates duplicate copies of repeating data to save storage capacity., capacity on demand , A service model where additional storage or processing power is pre-installed but only activated and paid for as business needs increase., perfomance, A measure of how quickly a storage system can read or write data, usually expressed in IOPS (Input/Output Operations Per Second) or throughput., hot vs cold storage, Hot storage is for frequently accessed data requiring high speed, while cold storage is for rarely accessed data where low cost is more important than retrieval speed., object storage , A flat data architecture that stores data as discrete "objects" with rich metadata and a unique identifier, making it highly scalable for unstructured data., file storage , A hierarchical data storage method where data is organized into files and folders, similar to how a local hard drive or office filing cabinet works., block storage , A high-performance storage method that breaks data into fixed-size "blocks," each with its own address, commonly used for databases and virtual machine disks., SDS , A storage architecture that separates the storage software from its underlying hardware, allowing for more flexible management and resource pooling..
