What Is The Cloud?

Where Did The Cloud Come From?

• We get the term “Cloud” from the early days of the internet where we drew a fluffy cloud to define a network of remote computers.

• 1st Cloud was TCP/IP, Networking Abstraction• 2nd Cloud was WWW , Data Abstraction

Our Cloud has evolved!

The cloud Today - Abstracts infrastructure complexities of servers. Heterogeneous platforms, Applications, and Data.

The Cloud – It’s Constantly Evolving.

• Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources. (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort, or service provider interaction.

• This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.

FIVE – Characteristics Of Cloud

1. On-demand self-service

2. Broad network access

3. Resource pooling

- Location independence

4. Rapid elasticity

5. Measured service

Three – Cloud Service Models

• Cloud Software as a Service (SaaS)– Use provider’s applications over a network

• Cloud Platform as a Service (PaaS)– Deploy customer-created applications to a cloud

• Cloud Infrastructure as a Service (IaaS)– Rent processing, storage, network capacity, and other

fundamental computing resources

Software as a Service - Definition

•Cloud Software as a Service (SaaS). The capability provided to the “end user” to use applications running on a cloud infrastructure and accessible from various client devices through a thin client interface such as a Web browser or application.•The consumer does not manage or control the underlying cloud infrastructure, network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

• Private cloud – enterprise owned or leased

• Community cloud– shared infrastructure for specific community

• Public cloud– Sold to the public, mega-scale infrastructure

• Hybrid cloud– composition of two or more clouds

Four – Cloud Deployment Models

The Cloud Framework

• GoGrid. It’s not a server sat under a developer’s desk in Minneapolis.

• Better Management Tools than EC2, Salesforce, and Rackspace.

• 24/7 Phone Support• 100% Uptime SLA• Dedicated Support Teams • f5 Hardware Load Balancing• Multiple Datacenter Provisioning

Which IaaS Does NBT Use?

GoDrid IaaS

• Cloud computing leverages:– Massive scale– Homogeneity– Virtualization– Resilient computing– Low cost software– Geographic distribution– Service orientation– Advanced security technologies

Positives to the Cloud

• Trusting vendor’s security model• Indirect administrator accountability• Loss of physical control• Data dispersal and international privacy laws

– EU Data Protection Directive and U.S. Safe Harbor program

– Exposure of data to foreign government and data subpoenas

– Data retention issues • Lease or Purchase Software
