Saas & DBaas

1. Introduction
What is it SaaS?

2. What is it SaaS?
Software as a service (SaaS), sometimes
referred to as "software on demand," is
software that is 100% deployed over the
internet.

3. What is it SaaS?
Software-as-a-Service (SaaS) is the
application layer of the cloud computing
model.

4. Cloud computing
• Cloud computing is a general term for the
delivery of hosted services over the internet.
• Cloud computing enables companies to
consume a computer resource, such as a virtual
machine (VMs), storage or an application, as a
utility -- just like electricity -- rather than having
to build and maintain computing infrastructures
in house.

7. Software as a Service
Software as a service: Pricing can be based on features,
storage capacity or on a per-user basis. Vendors
include Salesforce.com, NetSuite and Microsoft
Dynamics.
 Microsoft’s Office Web Apps.
 Dropbox.
 Google Drive.

8. Infrastructure as a Service
• Infrastructure as a service: Customers pay on a per-
use basis, typically by the hour, week or month.
Some cloud providers also charge based on the amount
of virtual machine (VM) space used.
• This model does not require users to deploy in-house
hardware and software.
• IaaS vendors include IBM, HP, Microsoft and Amazon
Web Services.

9. Platform as a Service
Platform as a service (PaaS): Can be priced per application/user
or gigabyte of memory consumed per hour.
PaaS vendors include Google, Oracle Public Cloud and Windows
Azure.

11. Saas advantages
• Access to unlimited Computing and storage
resources, made available and paid for only
as needed (Pay as you go).
• Decreasing cost.
• Increasing in control over the vendor
relationship.
• Focus on application and not on
infrastructure.

12. SaaS Testing
“The average enterprise IT department
devotes up to 50 percent of its entire
technology infrastructure to development
and test, with up to 90 percent of the
available test infrastructure remaining
idle”.
IBM Research

13. “Testing The Cloud”
• Testing applications which are in cloud or
migrating to cloud.
• Test the performance, reliability & security
of applications

14. SaaS Security Testing
 Test application security.
 Test network.
 communication security , Backup and storage policies, Controlled
access to sites and servers.
 Test for possible attacks.
 Test roles and privileges in multi-tenant environment.
 Test all the upgrades to detect broken security.
 Test data security / integrity among multiple tenants.

15. Conclusion
• Customers buy each month – keep them happy.
• SaaS is only a delivering model, customers will not switch to SaaS if
it is not better than traditional systems.
• Save time on support, maintenance, and upgrade, etc.
• Pay more attention to accessibility, security, deployments. The way
you earn reputation.
• Don’t buy cloud-based test solution just because you are testing
SaaS. In most cases, traditional test solutions work just fine and
save your 30% –50% cost.

16. What is DBaaS?

17. What is DBaaS?
• Database as a Service (DBaaS) is an
architectural and operational approach
enabling DBAs to deliver database
functionality as a service to internal and/or
external customers.

18. Why DBaaS?
• Optimization.
• Multiple Development.
• DBaaS supports flexibility and not impacted by:
o Resource Limitations
o Time Sensitive Projects
o Hardware limitations/budgets

20. Customers are dealing with:
• Application of a specific database.
• Massive growth in overall stored data.
• Increasing velocity of change in application layer.
• Challenges in supporting new technologies.
DBaaS providers solve most of these challenges for users.
