Comparison with physical servers DB

물리서버 컴퓨팅과 비교표
Classification Physical server-based Database ucloud DB
Cost Reduction - Purchasing cost for Hardware including spare capacity
Operation costs such as Network/Field/Electricity incurred
Sunk costs incurred when terminating a period necessary
- Use of capacity as much as needed, Charged by usage
- Reduction on additional operation costs
- No sunk costs incurred when terminating service
Extendability - Limited physical capacity on an existing system
- Addition/Replacement of Hardware required for expanding capacity
- Able to easily expand by adding virtual server(VM)
Promptness Installation time such as Delivery and Installation required - Service provided within 5 minutes by automatically assigning resources
- Providing ADMIN function as service
Stability Out of service with Hardware errors
- System Redundancy required in case of errors.
- Switch to spare Cloud resources, Prompt recovery from errors
- System Redundancy Unnecessary

Major Functions

  • 1 Providing Read Replica-based extendability
    As web applications are highly subject to horizontal expansion (Scale Out) due to characteristics of service, ucloud DB is equipped with extendability to respond to this trend In regard to extendability from the view of database reading and writing, most of web applications involve more reading operations than that of writing.
    To support this kind of characteristic, Read Replica-oriented expandability is provided.
    Function of creating Read Replica
    Function of controlling Read Replica
    Function of Creating/Deleting/controlling DB Instance
    Function of management and control in Replica Group
    Function of Binary Log management
  • 2 Supporting MY-SQL Multi Version
    It provides a function to add InnoDB engine of MY-SQL 5.5 version to service which is more stable than MY-SQL 5.1 currently offered by ucloud DB and is with 3-4 times stronger performance at maximum.
    Function to manage MY-SQL 5.5 template
    Function to manage MY-SQL 5.5 parameter
    Function to manage MY-SQL Multi Version
  • 3 Security Function Enhancement
    One of the biggest issues of Cloud service is security.
    By enhancing security for prevention of hacking on users' systems and enabling users to safely use service, users can take advantage of network security function which blocks inappropriate network access or permits network access only in a certain system.
    Function to manage database access control group
    Function of applying and managing rules on groups of access restrictions
    Management on item of DB Instance access control
    Function to issue and manage ucloud DB certificate
    Function to manage MY-SQL TLS secure access
    Function of firewall management
  • 4 Providing Open API function
    Functions of ucloud DB service currently provided by web portal are offered as Open API in accordance with KT standard.
  • 5 Providing high specification database VM
    High specification database VM(12vCore 32GB) of Scale Up structure is provided to customers demanding high-performance database.
    Supporting Cent OS(64 bit) 32GB memory
    Creating and managing high specification ucloud DB template
  • 6 Providing expansion in range of DB tuning parameter setting
    Database tuning parameters that customers can directly set are provided from expanding by 50 items.
    Function to set up MY-SQL 5.1 parameter added
    Function to set up MY-SQL 5.5 parameter added
    Providing record on additional parameter setting and function of application
  • 7 Advancement of user and administrator function
    Existing user UX is improved and API functions for admnistrators are provided.
