由 …衆ロ難τιáo~ 提交于 2019-11-27 16:18:54
We are working on rewriting our existing RIA and redesigning our database to re-architect it's design. Now we have 2 opinions about database: (This choices are for SaaS based hosting.) 1) Individual database for each customer. 2) Single DB for all customers. We are expecting good amount of data, some of our customers have db size ranging from 2GB to 10GB. # of tables are around 100. Can I get an answer about which choice we shall go for? We are not thinking about NoSQL solution as of now but we are planning to support about 4-5 databases with JPA (Java Persistence API) which includes MySQL,

随着互联网行业的高速发展，企业 IT 应用环境日趋复杂。几分钟的故障就会严重到用户体验，那么如何有效降低IT故障带来的影响呢？权威数据表明，86%的企业认为建立有效的监控系统和告警系统、提升 IT 的可见性是最佳的方式。 9月1日，国内第一个 SaaS 模式的云告警平台 OneAlert 宣布上线，该平台集成了国内外多种主流的监控和支撑系统，实现一个平台上集中处理所有 IT 事件，从真正意义上提升了 IT 可靠性。OneAlert 是国内应用性能管理领军企业 OneAPM 旗下的产品。 研发背景 其实，在 IT 运维支撑工作中，大多同学都使用了 Zabbix、Nagios 等开源监控工具或者是其他监控工具，他们经常面临着如何配置提醒通知的问题。 邮件通知，各工具配置都比较复杂，自建的邮件服务器还可能不太靠谱，而且邮件通知太慢了，主要是邮件客户端的接收延迟。 短信通知，复杂度太高，对接运营商短信网关，或者是使用短信猫方式，都需要开发配合。使用短信猫还面临在机房里面信号极其不稳定的问题。 其他？？想想而已～ OneAlert 是如何解决该问题的呢？在这之前，我们先说一个典故： 典故 1815年6月18日的滑铁卢战役，是拿破仑和威灵顿两国军队之间的生死交锋，一旦英国取胜，英国公债必然迅猛增长。拿破仑军队在傍晚时分败局已定，罗斯柴尔德法国家族收到现场情报反馈后

问题 We started to implement Stripe on Redsmin (one of our project) and I think we may have missed something. Here is how it works: To use our product, the user must select a plan (free, s, m, xl, xxl...) then enter its login/password and is then good to go for a free 30 days trial. When the user submits the form, our server calls Stripe create_customer with the specified plan and no credit card (because we want to offer 30 days free with no credit card required) and we update the user model on

Multi-tenant PHP SaaS - Separate DB's for each client, or group them?

由 风格不统一 提交于 2019-11-27 00:30:14
问题 You'll have to bear with me here for possibly getting some of the terminology slightly wrong as I wasn't even aware that this fell into the whole 'multi-tenant' 'software as a service' category, but here it does. I've developed a membership system (in PHP) for a client. We're now looking at offering it as a completely hosted solution for our other clients, providing a subdomain (or even their own domain). The options I seem to have on the table, as far as data storage goes are: Option 1 -
