Multi-Tenancy Models
Single Tenant
Multi Tenant
Single and Multi Tenant are the
two approaches that ISVs
typically take for delivering
their SaaS solution.
Single Tenant Solutions
typically involve setting up
separate instances for each
customer
Multi Tenant Solutions service
multiple customers (tenant)
from a single instance, there by
sharing all the hardware
resources

Scalability in Multi-Tenant Architecture
Why Scalability is critical for Multi-Tenant architecture?
Multi-Tenant systems experience heavy
load due to the fact that single instance
serves multiple customers
Load on the system is going to be
directly proportional to the number of
customers serviced.
SaaS Business model is only profitable
with higher number of customers.
Therefore, it’s suicidal if you are not
building a multi-tenant architecture that
is scalable at all levels.

Advantages of Cello and Azure Combination
Azure and Cello combination gives a perfect platform for ISVs to build
their product.
Cello brings in a wide range of engineering building blocks, operational
modules and subscription management tools. In other words, Cello offers
the complete SaaS Life Cycle Management Solution.
ISVs will have the option of exposing some of the Cello administration
features to tenants in the form self-servicing portal. This can bring down
significant amount of support team load.
Azure on the other hand provides infrastructure and application life cycle
management in the form of deployment support, monitoring tools,
online services, etc.
While Cello strengthens the product with a scalable and robust
architecture, Azure provides a scalable and secure infrastructure.

Typical Deployment in Azure
ISVs can choose to deploy their product in either web role/worker role
model or they can also choose the VM model (which is vanilla IaaS).
Cello is delivered in the form of APIs and libraries, which has to be
deployed along with the product. Web role will contain the Cello web
pages and binaries. Cello services will have to be deployed in Worker
role.
Cello data is maintained separately and will have to be setup in SQL
Azure database. However, the product database can point to any storage
technology offered by Azure.
Product can leverage all the services offered by Azure platform. Cello
does not bring in any limitations for the product.

Cello Offers Unlimited Scalability
Cello architecture is designed for unlimited scalability at all layers.
Products built using Cello design norms by default inherit the capability
to dynamically scale out without any coding efforts.
ISVs can initially start with a single sharded model. However, when the
load increases they can easily add additional resources in the form of
machines, databases, storage etc.
Azure Watch can be effectively utilized to monitor the load of the systems
and once the threshold is reached it will automatically add additional
machines.
Cello leverages Azure Data Sharding feature by abstracting the database
from Developers. This allows ISVs to shard by tenants and/or modules.

Benefits for ISVs
“The Techcello approach is likely to be ideal for companies -especially independent software vendors - that need to get to market relatively quickly with a multitenant SaaS solution and would like a substantial shortcut while avoiding lock-in to a proprietary application platform as a service (aPaaS)”
