Platform as a Service (PaaS)

PaaS provides all of the facilities (toolkits,building blocks, payment hooks) required tosupport the complete life cycle of buildingand delivering Web applications andservices entirely from the Internet.

Addressed to developers

Tenants have responsibility for their dataand applications & joint responsibility forthe framework.


Platform as a Service (PaaS) types

Comprehensive PaaS providers:They focus on supporting the wide range of languages and/or environments. A comprehensive PaaSvendor aims to address many scenarios and support as many different applications as possible. They presenta low lock-in factor.

– App Harbor, dotCloud, Engine Yard, Google App Engine, Jelastic, Microsoft Azure, Red Hat OpenShift, Uhuru

Specific-stack PaaS providers:They address to customers using specific, standard (usually enterprise-focused) stacks for applications andwant to take advantage of PaaS without completely rewriting the application. Addressed to already locked-inenterprises

– IBM (Java/DB2/WebSphere).

Proprietary PaaS vendors:They promise an extremely robust managed platform and service in exchange for embracing a proprietary scripting language and/or configuration. There is significant vendor lock-in risk since applications almost certainly will have to be rewritten to run it with any other vendor.

– Salesforce’s Force.com, Rollbase, WorkXpress


Platform as a Service (PaaS) services

A typical PaaS vendor provide a great variety of tools and services:• Languages and libraries/frameworks support

– Java: JavaEE6, Spring, Grails, Seam, Struts 2, Spring MVC

– Ruby: Rails, Sinatra

– Python: Django, Bottle

– PHP: Symfony, Zend, Cake, Smarty

– C#, F#, VB.NET: .Net, WCF, ASP.NET, ASP.NET MVC

– Javascript: Node.js

PaaS example: Red Hat OpenShift

Red Hat OpenShift is a developer friendly PaaS platform• requires less time for configuration• many typical systems administration tasks are automated

OpenShift is offered in to three flavors:• OpenShift Online: A cloud based, hosting service for application developers• OpenShift Enterprise: A PaaS platform designed to run within an organization’s data

center• OpenShift Origin: Open source application hosting platform underlying OpenShift Online

and OpenShift Enterprise

Architecture:• An application is a combination of code, configurations and cartridges. • Cartridges are high level services, (web servers, databases, logging tools, monitoring

tools etc.). They are logically isolated from one another and multiple cartridges can run on the same server.

• A broker manages provisioning and application management processes and communications with cartridges over a message bus.


PaaS example: Red Hat OpenShift

Infrastructure as a Service (IaaS)

IaaS provides the hardware resources (CPU,memory, storage, networking capacity) requiredfor the execution of Cloud applications.

Virtualization technologies are utilized forcreating Virtual Machines from physical servers,with the ability to scale services according tovarying requirements.

Addressed to system administrators

Tenants have responsibility for their data,applications and framework, and jointresponsibility with the providers on the operatingsystem.


IaaS services

A typical IaaS vendor provides a great variety of tools and services:• Computing and Networking

– Virtual Machines / Virtual Servers

– Virtual Private Cloud / Isolated Cloud Resources

– Automatic Scalability

– VM replication

– Elastic Load Balancing

• Storage and Memory– Capacity Scaling

– Data Replication (automatic Backups) and Redundancy (local or geographically distributed)

– Different types of service (Low-Cost Archive Cloud storage, Block storage volumes, hybrid Cloud storage)

– Import/Export tools for moving large amounts of data (data migration, content distribution, data recovery)

– Fast Cache: a distributed, in-memory, scalable solution that provides super-fast access to data

• Other services– Usage Monitoring

– Service Level Agreements (resources availability, performance, security, disaster recovery expectations, data location, data portability, support, exit strategy)

– Security (Physical level, Network level)

– Tools for Deployment and Management


IaaS example: Amazon EC2

Amazon EC2 is a Web service that provides resizable compute capacity• Reduces the time required to obtain and boot new server instances to minutes

– Instances are a combination of resources and software, including an operating system

• Allows quick capacity scaling as computing requirements change

• Only actual used capacity is billed

Amazon EC2 offers a number of different instance types:• General purpose: balance of compute, memory and network resources

• Compute-optimized: more CPU than memory resources

• Graphics Processing: GPU along with high CPU and network performance

• Memory-optimized: large memory sizes

• Storage-optimized: high disk I/O, CPU, memory and network performance

• Micro: low-cost , low CPU resources with the ability to increase in short bursts



Amazon EC2 offers the following features and tools:

• Amazon Elastic Block Store: offers persistent storage

• Elastic IP Addresses: associated with an account, not a particular instance

• Amazon Virtual Private Cloud: a logically isolated section of the AWSs

• Amazon CloudWatch: monitoring for Cloud resources and applications

• Auto Scaling: automatically scale capacity according to defined conditions

• Elastic Load Balancing: automatic distribution of incoming application trafficacross multiple instances

• High Performance Computing (HPC) Clusters: for complex computationalworkloads such as tightly coupled parallel processes

• VM Import/Export: tools for easy importing and exporting of existing VM images

• AWS Marketplace: online store for finding, buying and quickly deploying softwarethat runs on AWS



Amazon EC2 purchasing options:

• On-Demand Instances– Users that want the low cost and flexibility of Amazon EC2 without any up-front payment or

long-term commitment

– Applications with short term, spiky, or unpredictable workloads that cannot be interrupted

– Applications being developed or tested on Amazon EC2 for the first time

• Reserved Instances – Applications with steady state or predictable usage

– Applications that require reserved capacity, including disaster recovery

– Users able to make upfront payments to reduce their total computing costs even further

• Spot Instances– Customers bid for available capacity, and can access it when their bid is greater than the

current price

– Applications that have flexible start and end times

– Applications that are only feasible at very low compute prices


Network as a Service (NaaS)

NaaS provides network connectivity services(instead of computing, storage, platform orsoftware services) on a pay-per-use or regularsubscription basis.

Addressed to system administrators

Tenants and vendors have joint responsibility overtheir network.


Network as a Service (NaaS) characteristics

• In theory, NaaS users have access to additional computing resourcescollocated with switches and routers.

• Users can use NaaS:

– to implement custom forwarding decisions based on application needs (e.g. load-balancing, anycast

or a custom multicast service)

– to process packets on-path (modifying payload?) implementing efficient in-network services:

• data aggregation

• caching and redundancy elimination protocols

• Some NaaS service models:

– Virtual Private Network (VPN): Extends a private network and the resources contained in the

network across public or shared networks (e.g. the Internet).

– Bandwidth on demand (BoD): Network capacity is assigned dynamically based on users’ current

requirements.

– Mobile network virtualization: Mobile network capacity is provided to third parties (MNOs) and

charged based on their current needs. Usually providers use the existing infrastructure of MNOs.


Network as a Service (NaaS) benefits

• A business NaaS solution benefits:– Independence: Each user can have a logically segregated network.

– Bursting: Customers can buy capacity only when needed.

– Resilience: A variety of reliability treatments can be applied.

– Analytics: Vendors provide customers with detailed reports on how the service is

performing.

– Security: A variety of data protection solutions can be applied.


NaaS example: Aryaka NaaSAryaka NaaS addresses to enterprises looking to migrate their applications to cloud services and SaaS providers retaining

• Performance or network predictability

• Reliability

• Visibility

Aryaka’s NaaS supports all SaaS and cloud services: both majorplayers: e.g. Amazon Web Services (AWS), Google Apps and MicrosoftOffice 365 and any smaller public, private or hybrid clouddeployments.


NaaS example: Aryaka NaaSFeatures:• Core Network: A dedicated reliable, low latency core network with built-in diversity and

redundancy based on globally distributed points of presence (POPs) close to end userlocations.

• Guaranteed QoS: Support for industry standard QoS allowing predictable performance,independent of traffic offered from other applications

• TCP optimization: Connections between enterprise locations and Aryaka POPs optimizedto use available bandwidth and handle first and last mile packet loss. Connectionsbetween POPs optimized for high bandwidth, high latency transfers.

• HTTP/HTTPS optimization: Protocol proxies at POPs close to end user locations deliverobject caching, compression and persistent connections to accelerate performance,reduce origin site bandwidth consumption and lower origin server utilization

• Security: Enterprise-grade IPsec between customer locations, POPs and cloud providers.POPs at SSAE 16 compliant Tier 3 / Tier 4 data centers with biometric entry systems

• Centralized WAN and application layer visibility through the web-based MyAryaka portal

• 24/7 support via Network Operations Centers located on opposite sides of the world
