Executive Summary

Have you ever tried sifting through the hundreds of cloud solutions available in todays

market? Several years ago cloud computing was touted as the next major advance inIT. There was a huge influx of services and solutions from companies that already had

infrastructure to spare, and from scrappy startups that could just build their cloud serviceson top of other larger cloud services.

DZone Research expects the number of new cloud products to continue growing. There are

already so many categories of cloud providers that its hard to know if youre researching the

right ones for your use case. How do you distinguish the contenders from the pretenders?

Even if you have nailed down the type of cloud provider you need, youre still facing a litany ofchoices.

The cost and time savings of choosing the right cloud provider can revolutionize your

business and drive signicant new prot, but the selection process is daunting. DZoneobserved many developers and IT professionals struggling to nd the right solution for theirorganization, so we decided to mount this unprecedented research project to create the

Denitive Guide to Cloud Providers. We hope it helps you.

ObjectiveDZones Denitive Guide to Cloud Providers is tailored to answer your questions about the

many types of cloud services and to remove the obstacles preventing you from nding the

right cloud computing solution for your organization. This guide will help you answer two

major questions:

1. What type of cloud service is the best t for my use case?

2. How does each cloud product compare to other offerings in the same category?

FeaturesDZone Research has compiled vendor interviews, feature lists, trends in the IT community,

and expert opinions into this one comprehensive guide so that you dont have to spend

Introduction

This guide is a tool for navigating the major PaaS and IaaS categories and matching thesolutions to your needs. It will help you answer two major questions:

1. What type of cloud service is the best t for my use case?

2. How does one cloud product compare to other offerings in the same category?

With our simple comparison grids and product description pages, which include unbiased,third-party reviews, youll be able to make a well-informed, data-driven decision about thecloud services you want to adopt.

The most common examples of cloud services are Software-as-a-Service (SaaS),

Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS). The combined use ofthese three is sometimes referred to as the SPI model (SaaS, PaaS, IaaS).

These categories above are generally well-known and well-dened within the tech industry,but there are countless offshoot categories and subcategories of IaaS, PaaS, and SaaS,including Storage-as-a-Service (STaaS), Communications-as-a-Service (CaaS), Network-as-a-Service (NaaS) and Monitoring-as-a-Service --(MaaS).

For this guide weve interviewed vendors, researched features, polled our massive softwareengineering community, and collected expert opinions so that you can quickly and easilymake a decision about the products you want to adopt with the research to back it up.

How Was This Guide Created?

DZones 2013 guide to PaaS and IaaS solutions was created to help IT professionals makethe best decision concerning what cloud services to adopt. DZones goal is to give the most

well-rounded view of PaaS, IaaS, and other cloud services using three main informationsources:

1. A survey of 400 DZone Audience members about their feature preferences for cloudservices.

2. Security, scalability, usability, and pricing data collected directly from cloud servicevendors.

3. Polling data from topic experts to provide unbiased, third party reviews. The experts

also reviewed this guide.

How to Use This Guide

What this guide covers

The scope of this guide includes severalmajor categories of Platform-as-a-Serviceand Infrastructure-as-a-Service:

General PaaS APaaS Open-source PaaS Language-Specic PaaS Private PaaS IaaS Build Your Own IaaS BaaS/MBaaS

Multi-Cloud AMP

What this guide does not cover

A guide covering every single type of cloudservice would be too bulky for many readers,so there were many categories that DZoneopted to leave out of this guide. These topics

may be covered in future guides.

SaaS (Software-as-a-Service) MaaS (Monitoring-as-a-Service) DBaaS (Database-as-a-Service) Cloud CDNs STaaS (Storage-as-a-Service) CaaS (Communications-as-a-Service) NaaS (Network-as-a-Service) iPaaS (Integration Platform-as-a-

Service) Cloud IDEs (Integrated DevelopmentEnvironments)

This guide has several sections listed in the index that provide various forms of informationabout cloud computing topics and cloud offerings:

Introduction: The opening sections provide background information to help youdistinguish various subcategories for cloud platforms.

Comparison Grids: A side-by-side feature comparison of various cloud solutions. Thereare individual data tables for each cloud subcategory.

Solution Descriptions: These single page data sheets list the main features for a singlecloud vendor. Some also include Pros and Cons from third-party reviewers. DZonespool of reviewers did not review all of the solutions in this guide. They only reviewed

solutions that they had used previously.

Cloud Glossary: A dictionary for terms related to cloud computing.

How to Read theComparison Grids

DZone gathered data directly from each vendor represented in this guide. (A handful of vendorselected not to contribute data at this time, and these vendors are absent from the 2013 guide.)

The entries in each column come directly from the vendor. DZone made very few modicationsto this data.

The entries in each column come directly from the vendor. Blank cells indicate either a featurethat is not applicable to the cloud solution in question, or that the vendor did not provideinformation about that feature.

Each subcategory has its own separate comparison grid for a more balanced analysis between

similar offerings.

Differences BetweenPaaS and IaaS

While PaaS and IaaS are similar in many respects, there are signicant differencesbetween them. Where IaaS essentially provides raw computing resources, PaaS providescustomers with software, Virtual Machines (VM), and typically handles all aspects of systemadministration for the customer. So while IaaS and PaaS both provide the customer withcost-saving, scalable cloud infrastructure, PaaS provides additional middleware utilities ontop of the common IaaS services. The PaaS model can do everything the IaaS model can do,with the added benet of managing underlying resources, application frameworks, and tools.

Private vs. Public Clouds

The terms public and private refer to two deployment models of a platform-as-a-service orinfrastructures-as-a-service. Public clouds are shared infrastructure platforms provided by athird party, which allows greater cost savings and hands-off administration. But since public

cloud data may be housed in any number of physical locations, the customer may be forcedto share resources with other users. This may present challenges in certain use-casesoutlined in the comparison points below.

Private clouds may be physically located in the customers data center, or they may beadministered by the vendor as a Virtual Private Cloud (VPC). In a VPC, the servers in questionare isolated from public servers and used exclusively by one customer. The distinguishingfeature between private and public clouds is exclusivity. When weighing private and publicoptions, you will also want to consider the following:

Private Cloud Public CloudPros On-premises datacenters are more likely to pass the

most stringent security compliance standards andregulations

More customizable than public clouds on the mostgranular levels of hardware and the operating system

VPCs and hybrid clouds can provide some of thescaling and convenience of public clouds along withisolation from other customer instances

Certain types of software work better in dedicatedenvironments.

No up-front investment Predictable pay-as-you-go pricing

models Fast setup and scaling Flexible infrastructure that can make

changes quickly based on changingneeds or swings in trafc

Cons Larger up-front investment Much slower to get up and running on-premises

Requires more administrators with technicalprociency

Even the best administered on-premises datacenterscant match the scalability and elasticity of mostpublic clouds.

Customers must handle their ownspecial security concerns

Less customizable than Private on themost granular levels of hardware andthe operating system

Public cloud providers dont guaranteedata safety sufciently enough to meetcertain regulations.

Certain types of software dontfunction optimally in shared, virtualizedenvironments.

Public and private clouds both have their place in the industry. If you have to pass strictregulations and security audits, or you have software that doesnt work well in shared

environments, private cloud may be your only option. If your organization already has aninternal data center and a dedicated operations team, an on-premises cloud is probablyfeasible, but if you dont have these resources, theres also a middle-ground (but sometimesmore complex) option: VPCs or hybrid cloud.

If you really want to take full advantage of cloud benets like limitless scalability andelasticity without a lot of customization effort, then public cloud is your best bet. Commonuse-cases for public clouds include research computing, web applications, and test ordevelopment environments.

12/101

What is PaaS?

Platform-as-a-Service (PaaS) is one of the three major categories of cloud computingservices (along with IaaS and SaaS). PaaS provides the customer with the requisite hardware

architecture (the platform) and software subsystems and components (the solution stack)to deliver the customers product or service. In a PaaS model, the customer uses toolsand libraries from the provider to build the software implemented on the PaaS platform.Depending on the tools that the provider supports, the customer can sometimes implementtheir own custom stack of development tools.PaaS is appealing to clients who dont want to devote resources to hosting, maintaining, andmanaging the underlying hardware and software used in the implementation of their serviceor product. PaaS is composed of an operating system and middleware (software that allowsapplications to run on the cloud), with the provider handling security and scaling. With aPaaS model, the client is free to focus on its application and its customers. The developmentenvironment is set up and automatically maintained, from hardware to tooling.

Benets

Speed of development: customers can spend more time developing their applicationand less time managing hardware and software.

Cost: The PaaS model allows the customer to consume resources on-demand, reducingoverhead cost by preventing the customer from investing in additional hosting capacity

that may go unused. A PaaS also eliminates the overhead cost of maintaining hardwareand software.

Scalability: As the load fluctuates, the PaaS model allows infrastructure to scalecomputing resources to meet demand while facilitating uninterrupted end-userexperience.

Downsides

Less Flexible than IaaS: A PaaS typically handles or streamlines more of the

complications in building software and maintaining the development environment, butthe downside is a more prescriptive framework. Your development team may needmore control over the inner workings of their environment than a PaaS allows. In mostcases, the more complexities your cloud service handles, the less control you have overyour development process.

Subcategories of PaaS

APaaS (also spelled aPaaS)Application Platform-as-a-Service (also called Visual aPaas by some) is a subcategoryof PaaS that is often lumped into the PaaS category with other solutions that provide moreflexibility and a larger array of middleware than APaaS. APaaS, does not provide the samelevel of flexibility as a general PaaS. APaaS tends to be built within a proprietary frameworkof developer tools and often features its own ecosystem and marketplace for distributing andrunning the apps in the enterprise. Here are some more dening traits of an APaaS:

Extreme ease of use, enabling rapid development (sometimes point-and-clickdevelopment) processes.

Some APaaS offerings allow users to create and manage business objects, not code, sosoftware development expertise is not required to create an application.

The simplest description of APaaS isAbhishek Ghoshsdenition: The user is moreconsumer than a developer. The main advantages of an APaaS are having a hands-offsoftware development environment and allowing non-technical, business-level employeesto create applications. Some examples are Force.com, which is an ecosystem for theSalesforce.com Software-as-a-Service.

Benets

Rapid Development: The friendly interface and the limitations of what can be built makedevelopment much simpler and more streamlined.

Simplicity: Nearly all of the development and operational complexities are handled bythe platform.

Downsides

Minimal Flexibility:If a non-technical employee will be developing applications withAPaaS, their ability to implement nely-customized features will be very limited.

Prescriptive Environment:The proprietary environment of APaaS offerings often placestrict limits on the tools and programming languages your developers may use, limitingthe range of applications they might create.

14/101

Open Source PaaS

Open Source Platform-as-a-Service is a more flexible, community supported cloudmiddleware platform that can be deployed on a variety of cloud infrastructures, public orprivate. Many open source solutions also support a diverse array of languages, frameworks,and databases due to community-built utilities that plug into the platform. The platform isfree-to-use and great for companies that need a specic architecture or mix of tool support.With an open source PaaS, you can custom-build a PaaS that meets your precise needs.

The most well-known Open PaaS solutions are driven by developers from a stewardcompany, while community developers outside of the company contribute to the platformas well. In this way, open source platforms benet from both the steady foundation of adedicated team as well as expanded support and implementation of more niche features byan enthusiastic community.

Major Open Source PaaS offerings include:

OpenShift Origin - RedHat Cloudify - GigaSpaces

Benets Free and Open Source: Even though you have to pay for the infrastructure that you use,

the platform software is free to use. Because its open source, you can modify thesoftware in just about any way you choose.

No Lock-in: Not only can you choose from use a wide variety of cloud infrastructures,you can also move your platform easily from one cloud to the next if your currentinfrastructure doesnt suit your needs.

Downsides More Work: You have to set up your own middleware environment, but once you have it

set up your development workflow will be more streamlined than just working straightoff of an IaaS.

Dependent on Community: Although a steward company usually keeps an open source

platform moving forward, the quality of the ecosystem depends greatly on the activity ofthe community, which can vary.

8/13/2019 PaaS IaaS Guide 06072013

15/101

Language-specic PaaS

In most discussions of the PaaS market, language-specic offerings go undifferentiatedfrom their competitors. This guide draws a distinction, however, between language-specicand non-language-specic solutions. Numerous PaaS offerings only support one or two

programming languages (and some related tools) natively, without the help of third-partyadd-ons.

If a vendor has chosen to make a PaaS that focuses on one language and one technologyecosystem, it can often be a strength of the platform rather than a weakness. If yourengineering team primarily uses a particular set of technologies for development, like Javaor Node.js, there are PaaS solutions focused specically on those technologies that couldprovide several benets which PaaS solutions with more generalized support may notallow. Jelastic is one example of a Java-specic PaaS, while Nodejitsu is a Node.js-focused(server-side JavaScript) PaaS.

Benets Better Language Support: In many cases, the PaaS vendors that are focused on a

specic languages ecosystem provide rst-class support for that technology stack.

Downsides Narriow Choices:If you choose a language-specic PaaS, you should be certain that

your developers wont need to change their programming language ecosystem for

several years, because you wont be able to continue using the PaaS if you decide tostart building with other ecosystems, unless the vendor, or a 3rd party add support.

Private PaaSEarly on, the major PaaS players were generally public cloud services, but many PaaSproviders now offer private or hybrid cloud platforms as a service in addition to publiccloud offerings. The advantages of public vs. private cloud deployments are outlined in ourPrivate vs. Public PaaS section. Some of the major private-enabled PaaS providers includeWSO2 Stratos, OpenShift Enterprise, CumuLogic, and Apprenda.

What is IaaS?

Among the three main categories of cloud computing services, Infrastructure-as-a-Service,or IaaS, can be considered the most basic and the most flexible. The IaaS cloud-computing

model provides clients with the scalable hardware architecture they need to implement theirown middleware and software on which to run their application. An IaaS provider deliverson-demand and scalable cloud infrastructure based on various operating systems, usuallyincluding Windows and Linux.IaaS is ideal for a customer that wants to implement their own software infrastructure andhandle their own system administration, while not having to worry about housing, conguring

or updating physical servers.

Benets Customization: Since IaaS is just hardware and an operating system, the customer is

free to create and modify all aspects of the development environment and softwarearchitecture as they see t.

Scalability: IaaS scales resources to meet demand as load fluctuates, while facilitatinguninterrupted end-user experience.

Cost: The IaaS model allows the customer to consume server resources on-demand,so they dont have to buy more hardware during periods of increasing server load. AnIaaS also eliminates the overhead cost of maintaining servers and updating operating

systems.

Downsides More Work: Although you save money for the on-demand usage pricing with most IaaS

solutions, and the hosting and physical maintenance is done for you, you still have tobuild, congure, and maintain your own middleware stack of development tools.

8/13/2019 PaaS IaaS Guide 06072013

17/101

Subcategory of IaaS

Build-Your-Own IaaSBuild-Your-Own IaaS is essentially software that lets you build your own Infrastructure-as-a-Service by deploying and managing large networks of virtual machines. There areboth commercial offerings and open source, community-developed offerings of this typeof software. You can download the software and transform your own servers into aninternal IaaS cloud, or you can nd a service provider that offers public cloud services thatare built using this software. There are also commercial offerings of Build-Your-OwnIaaS. OpenStack, CloudStack and Eucalyptus are the main players in the open source Build-Your-Own IaaS space. VMwares vCloud is a commercial variant of Build-Your-Own IaaSsoftware. RedHat, Rackspace and Citrix are companies that provide pre-built IaaS offeringsthat were constructed using software such as OpenStack and Cloud Stack. The technical

specications and APIs of these Do-It-Yourself clouds are very similar to the Amazon WebServices specications, and as a result they can form hybrid clouds with services such asAmazon EC2 and S3.

Benets Free and Open Source: You have the flexibility to modify the software in just about any

way you choose. You also wont be paying anyone except your own developers to usethis.

No Lock-in: Put your DIY IaaS on just about any infrastructure, internal or external.

Downsides More Work: You have to set up your own cloud and handle your own administration,

but there are many ways to streamline the deployment process with your owncustomizations. However, the pure open source software can also be user-friendly.

Dependent on Community: Although a steward company usually keeps an open sourceplatform moving forward, the quality of the ecosystem depends a lot on the activity ofthe community, which can vary.

What is BaaS/MBaaS?

Backend-as-a-Service, also called Mobile Backend-as-a-Service, is a specialized cloudutility that allows customers to connect their web and mobile applications to cloud-based

databases and provide user management, push notications, and integration with socialnetworking services. These services are made available through software development kits(SDKs) and application programming interfaces (APIs).

Having a BaaS greatly simplies and accelerates development and implementation ofthe previously listed services because without one, developers would need to separatelyincorporate each API into the app. Using a BaaS, developers can work with one unied APIand SDK.

The BaaS marketplace is highly competitive, which is great for buyers.

What is Multi-Cloud AMP?

Multi-Cloud Application Management Platforms are a subcategory of Software-as-a-Serviceaimed at managing a large amount of applications that are running on an IaaS. They also

allow you to more easily administrate the IaaS resources that you are currently using. IaaSsolutions like Amazon Web Services have many different services, and AMPs let you managethese as well. Some solutions also assist customers in building and managing private cloudinfrastructures.

A Multi-Cloud AMP is the weapon of choice for the IaaS customer who is having difcultymanaging a growing number of cloud services. The commercial offerings in this spaceinclude RightScale and Cloudsoft AMP, and there are also open source offerings in this space,like Scalr.

Audience Survey Results

The purpose of DZones PaaS and IaaS community survey was to determine the usagepatterns and preferences of various IT professionals. The DZone community includesdevelopers, designers, managers, system administrators, and others, with 79% of

respondents dening their primary role as development. From prior community surveys,we have learned that DZone readers typically participate in company buying decisions andhave worked with a wide range of PaaS and IaaS providers.

We asked our respondents about their primary concerns surrounding cloud computing,how buying decisions are made within their companies, best ts for their organizations,preferred languages and frameworks, and perceived benets and challenges.The DZone community is experienced with cloud technologies:71% have used a cloud toolor service professionally, and 36% do so regularly.

Developers want a polyglot cloud:We found that on average, the companies represented byour survey require support for four programming languages in a PaaS solution.Close contestPublic vs. Private vs. VPC vs. Hybrid:Security emerged as a primaryconcern, which means that professionals will sometimes assume that private cloud stylesare the safest option even though many experts assert that public clouds can be justas secure. Despite this common assumption, all four cloud types had relatively equalnumbers of supporters.

Performance is an obstacle to adoption:53% of respondents reported that they were

currently experiencing performance-related issues with a cloud service. 48% reported thatthey expected to experience such problems in the future.

Cost is an unexpected challenge:45% of respondents expected challenges while managingcloud costs, but 57% said they were currently experiencing cost issues. This was thelargest gap in expectations.

Cloud outages are the biggest concern:Although only 24% of respondents were affectedby a cloud outage last year, uptime was the most important feature for them. Of thoseaffected, 53% were affected for 8 hours or less, and 18% (4% of total the response pool)were affected by an outage lasting more than 12 hours

The OpenShift PaaSarchitecture allowsa number of optionsfor data locality andsecurity. Data canbe located on theunderlying infrastructure

that supports the PaaS,or it can be located inexternal systems thatare accessed by thePaaS, depending on yoursecurity requirementsand data localityrequirements.

A variety of networkand data managementtechniques are used tokeep information secureincluding SSl for anyapp, security audits andmonitoring.

SSL for all apps on--.clvereapps.io domain,all apps run on their ownVM, backups every dayfor data repository, andintensive monitoring.

Separation on a perdeployment basis withLinux Containers (LXC).All users are unprivilegedaccounts without accessto the host system.

Application isolationis achieved usinglight weight, softwarevirtualization. dotClouduses GRSEC, a hardenedlinux kernel sharedacross all the containers

with no overhead. Eachservice runs on its ownseparate container.

Data is stored inseparate access-controlled databasesper application, eachrequires a unique login.Multiple applications anddatabases are assigned

separate databases andaccounts to mitigatethe risk of unauthorizedaccess.

Servers are provisioned withadditional persistent storagedevices; data stored in thedatabase are kept on thesedevices and frequently backedup. Each customer is locatedin its own AWS security group,

with their own instances.Instances are not shared.Backup can be encryptedusing GPG.
