Introduction

What is it SaaS?

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.

What is it SaaS?

Software-as-a-Service (SaaS) is the application layer of the cloud computing

model.

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.

Cloud Computing

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.

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.

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.

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.

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”.

“Testing The Cloud”

• Testing applications which are in cloud or migrating to cloud.

• Test the performance, reliability & security of applications

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.

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.

What is DBaaS?

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.

Why DBaaS?

• Optimization.• Multiple Development. • DBaaS supports flexibility and not impacted by:

o Resource Limitations o Time Sensitive Projects o Hardware limitations/budgets

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.
