multi tenant database

This results in lower per-tenant expenses. Therefore, although data is isolated, sharing resources might make it difficult to honor the Service-Level Agreement. Enterprise customers from around the world are consolidating their Oracle Database environments using Oracle Multitenant to achieve greater operating efficiencies and lower costs. When the data is stored in a single database, a global query filter can be used to automatically filter rows by the tenant ID column, ensuring that developers don't accidentally write code that can access data from other customers. Some strategies have been implemented to manage multi-tenant application deployment. Is Creativity Crucial In Todays Business Environment? Each object (table, index, LOB) is stored in a partition. That way you can have all the data of all the companies in the same table / database and at application level you can control what company is tied to which companyId and determine which data to display for certain company.

This design facilitates tenant data to be distributed across multiple databases (shards), with all the data for a particular tenant is all contained in a single shard. If you can imagine a "shared everything" system on a single server, recovering data for a single tenant means recovering just some of the rows in every shared table. Because the tenant's instances are separated, if some issue arises with one tenant's database, the application will continue working for all the other tenants.

When the number of tenants/clients on the app is small, this design is effective but when tenants are larger, resources compromisation is bound to occur. This ensures that there will be no tenant-specific functionality across the different application domain layers.

The following are the 4 approaches I will cover in this blog post: Risk of exposing one tenant's data to another tenant or updating the wrong tenant's data (e.g., if a developer misses a WHERE clause to filter on the tenant id), One database schema to maintain and a simple schema update rollout processit only needs to be applied once, Manage the High Availability/Disaster Recovery/maintenance operation/monitoring strategy for just one database, Limited development/application code complexitysingle schema, single database to connect to, Adding new tenants is easyno processes needed around database/schema provisioning or connection determination, Any query or data modification includes a predicate to restrict the operation to a specific tenant id, Must remember to update the RLS policy as new tables are added over time, Can't easily restore a single tenant's data, Limited to scaling-up hardware, rather than scaling out, Risk of "noisy neighbors"tenants can impact the performance of the system for all others due to a lack of isolation and all competing for the same resources, One-size-fits-all performance tuning and stabilitytenants' data volumes and usage can vary dramatically, impacting things such as execution plans making it more difficult to optimize performance across every tenant, As the number of tenants and data per tenant grows, maintenance activities take longer, potentially impacting all tenants, Tenant data has some more isolation (but still within the same database), No RLS needed; reduced risk of missing a WHERE clause to limit to specific tenant's data, Still a risk of querying the incorrect schema (e.g., specifying the schema for an object when it should have instead come from the user account's default schemausual best practice is include schema prefixes, which can feel unnatural), 1 database to manage High Availability/Disaster Recovery/maintenance operation/monitoring strategy for, Extra scope and control over some tenant-specific maintenance activities, Schema updates more involved, needing to be rolled out to n tenants, Can't easily restore a single tenant's data (although it's a slightly better process than approach 1 due to isolation of tenant data), Adding new tenants is more involved as new schemas/user accounts need to be created, As the number of tenants grows, there will be a lot of database objects being created to manage and maintain, Data is partitioned into smaller tables, with smaller indexes, Optimizations could be made at an individual tenant's schema level, Risk of "noisy neighbors"tenants can impact the performance of the system for all others due to limited level of isolation and all competing for the same resources, Highest level of tenant isolation, supporting options for shared server and/or isolated servers, Potentially more servers to patch and keep secure, Maintenance jobs can be managed and customized per tenant, Can easily restore/relocate/clear down a tenant's data, Adding new tenants is more involved, as new schemas need to be created, As the number of tenants grows, there will be more databases being created to manage and maintain, Some added complexity to maintain a registry of tenant-db mappings/application code to determine which connection to use, Scale-out and scale-up are both optionstenants can be spread over multiple servers, Choose to balance between cost (higher tenant density/fewer servers) and performance (lower tenant density/more servers), Some tenant isolation possible in general over approach #1, Tenants still share a database and schema with others (same RLS mitigation applies as approach #1), Choose to balance between overhead of more databases to maintain (lower tenant density) versus fewer (higher tenant density), Possible to relocate a tenant's data (although harder than approach #3), More maintenance overhead than approach #1, Scale-out and scale-up are both optionstenants can be spread over multiple servers. The focus of multi-tenancy can vary from security, maintainability, reduced .
