????Each edition offers different features and levels of support.

Enterprise Edition

????The Enterprise edition (EE) represents the latest, most stable, production-ready release of Couchbase Server. We recommend the enterprise edition binaries for commercial production systems running Couchbase Server. The enterprise edition contains some unique features that make it the best fit for production deployments running in data centers or a public cloud infrastructure. Use of EE in development and test environments is free. EE requires a paid subscription for production use. Our?paid annual subscriptionsfor EE include a commercial license, better availability capabilities, enhanced security features, advanced tooling and higher performance and scale. It also includes technical support with service level commitments via our 24x7 support organization and hot fixes for releases. One important principle for CE and EE is to ensure full portability of applications between two editions. The capabilities ensure that an application running on EE should simply transition to CE without code changes and visa versa.

? ??企業(yè)版(EE)代表了Couchbase Server最新的、最穩(wěn)定的、可生產(chǎn)的發(fā)行版。我們推薦運(yùn)行Couchbase Server的商業(yè)生產(chǎn)系統(tǒng)使用enterprise edition二進(jìn)制文件。enterprise edition包含一些獨(dú)特的特性，最適合在數(shù)據(jù)中心或公共云基礎(chǔ)設(shè)施中運(yùn)行的生產(chǎn)部署。在開(kāi)發(fā)和測(cè)試環(huán)境中使用EE是免費(fèi)的。EE需要為生產(chǎn)使用付費(fèi)訂閱。我們每年為EE付費(fèi)訂閱的服務(wù)包括商業(yè)許可、更好的可用性、增強(qiáng)的安全特性、先進(jìn)的工具以及更高的性能和規(guī)模。它還包括通過(guò)我們的24x7支持組織提供的技術(shù)支持和服務(wù)級(jí)別承諾，以及版本的熱補(bǔ)丁。CE和EE的一個(gè)重要原則是確保兩個(gè)版本之間的應(yīng)用程序具有完全的可移植性。這些功能確保在EE上運(yùn)行的應(yīng)用程序應(yīng)該簡(jiǎn)單地轉(zhuǎn)換到CE，而無(wú)需更改代碼，反之亦然。

Community Edition

????The Community Edition (CE) is best for noncommercial developers where basic availability, performance, scale, tooling, security capabilities and community support is sufficient. CE comes free and there are no constraints on using these binaries in production systems. However, CE is not subjected to the iterative "test, fix, and verify" quality assurance cycle that is a part of the enterprise edition release process. The release version of CE is several months behind EE. CE also do not include the latest bug fixes. Documentation, mailing lists, and forums provide support for the Couchbase user community to help troubleshoot issues and answer questions.

Open source project?開(kāi)源項(xiàng)目
