Cloud database architecture needs
with the development and popularity of cloud architecture, business processes and applications in the "cloud" of, the cloud database because an important position in the overall architecture of the importance of the cloud transformation in the self-evident . Cloud database needs to meet these technical requirements, in addition to the specific upgrade in functionality, the overall architecture more needs to be upgraded and "evolution."
Cloud database architecture is its ability to carry Application Architecture "cloud" of the key points, with the development of technology and business, architecture cloud database appeared in several major direction of development:
• In dbPaaS platform, computing - storage layer separation It will become a mainstream technology direction. , Calculation and underlying storage module decouples the internet cloud database storage tier by fragmentation protocol analysis to achieve a level of elasticity of the expanded storage, while the layer is calculated by a stateless design allows increasing the number of layers is calculated to enhance the computing nodes linear , it has reached the level of the entire database elastic cloud platform expansion.
• Multi-mode architecture become a mainstream trend, Multi-model architecture in a database platform can support a variety of storage, greatly reducing the cost of operation and maintenance and development. Traditional databases such as IBM, Oracle and other relational already provided, OO, and even XML storage engines. The new generation is more databases provide NewSQL, JSON, FIG object store other types of data storage engine.
• cloud database platform will provide a variety of mixed-mode data services - relational and non-relational. This mode allows the user to combine different types of data storage characteristics in the same platform, providing a hybrid data storage solutions for the next generation IT applications.
• more in line with the requirements of micro-services business architecture, micro-service requirements as far as possible and loose coupling between the various services can be independently expansion module. So for the database, will also for different business, focusing on different configurations, either the traditional "read and write separation" or the now popular around this requirement HTAP are expanded.
Cloud architecture, virtualization, database, containerization has become the very basis of technical competence.
SequoiaDB virtual machine images on line
as a representative of distributed database products under the cloud architecture, SequoiaDB and cloud services for micro-architecture, offers a variety of technical features:
l MySQL protocol level compatible: The "computing storage separation" architecture to achieve 100 % MySQL syntax compatible, existing applications can be smooth and seamless migration.
financial level distributed OLTP: ACID support in a distributed architecture, full support for distributed transactions, consistent with strong, multi-copy high availability to meet the needs of distributed core trading business.
native Distributed architecture: distributed architecture engine using native database support elastic expansion of PB-level data, to effectively deal with massive data growth, no single point of failure in a distributed high availability.
multi-mode data engine / HTAP: Multimode (Multi-model) data storage engine that supports cloud-based unified management of multiple types of data under the framework, HTAP help online transactions, physical isolation off-line analysis business, without disturbing each other.
Demand for rapid deployment and use of distributed database SequoiaDB, but also for the convenience of the user experience fast, SequoiaDB giant sequoias database updated database mirroring based virtual machine. Users can download and tutorial using pre-configured installation SequoiaDB Sequoia database pseudo-cluster environment, to quickly understand the capabilities and technical characteristics of the database.
Virtual machine images can be downloaded and used to access:
