Cloud Computing – Types of Cloud

March 19, 2013 Published in: Cloud Author: Goran Čandrlić

Cloud computing is usually described in one of two ways. Either based on the deployment model, or on the service that the cloud is offering.

Based on a deployment model, we can classify cloud as:

  • public,
  • private,
  • hybrid
  • community cloud

Based on a service the cloud model is offering, we are speaking of either:

  • IaaS (Infrastructure-as-a-Service)
  • PaaS (Platform-as-a-Service)
  • SaaS (Software-as-a-Service)
  • or, Storage, Database, Information, Process, Application, Integration, Security, Management, Testing-as-a-service

Previously, we have explained how cloud works. Basically, programs that are needed to run a certain application are now more popularly located on a remote machine, owned by another company. This is done in order not to lose on the quality performance due to processing power of your own computer, to save money on IT support, and yet remain advantageous on the market. These computers that run the applications, store the data, and use a server system, are basically what we call “the cloud”.

 

Where Do I Pull the Switch: Cloud Location

Public Cloud

When we talk about public cloud, we mean that the whole computing infrastructure is located on the premises of a cloud computing company that offers the cloud service. The location remains, thus, separate from the customer and he has no physical control over the infrastructure.

As public clouds use shared resources, they do excel mostly in performance, but are also most vulnerable to various attacks.

GlobalDots offers worldwide Public Cloud service in leading data centers. Our experts will assist you in choosing the right solution for you.

Private Cloud

Private Cloud provides the same benefits of Public Cloud, but uses dedicated, private hardware. Private cloud means using a cloud infrastructure (network) solely by one customer/organization. It is not shared with others, yet it is remotely located.  The companies have an option of choosing an on-premise private cloud as well, which is more expensive, but they do have a physical control over the infrastructure.

The security and control level is highest while using a private network. Yet, the cost reduction can be minimal, if the company needs to invest in an on-premise cloud infrastructure.

GlobalDots offers worldwide private cloud service in leading data centers.

With our Private Cloud you’ll get:

  • Increased redundancy
  • Decreased provisioning time for new servers
  • Saved capital by eliminating hardware support contracts
  • Quicker expendability compared to hosting your own physical servers
  • Use of dedicated, private hardware

Hybrid Cloud

Hybrid cloud, of course, means, using both private and public clouds, depending on their purpose.

For example, public cloud can be used to interact with customers, while keeping their data secured through a private cloud.

Most people associate traditional public cloud service with elastic scalability and the ability to handle constant shifts in demand. However, performance issues can arise for certain data-intensive or high-availability workloads.

GlobalDots offer combines hybrid cloud with bare-metal and virtualized clouds into a unified environment allowing your business to optimize for scale, performance and cost simultaneously.

Community cloud implies an infrastructure that is shared between organizations, usually with the shared data and data management concerns. For example, a community cloud can belong to a government of a single country. Community clouds can be located both on and off the premises.

What Can I Do With It: Cloud Service

The most popular services of the cloud are that of either infrastructure, platform, software, or storage.

As explained before, the most common cloud service is that one offering data storage disks and virtual servers, i.e. infrastructure. Examples of Infrastructure-as-a-Service (IaaS) companies are Amazon, Rackspace, Flexiscale.

If the cloud offers a development platform, and this includes operating system, programming language execution environment, database, and web server, the model is known as Platform-as-a-Service (PaaS), examples of which are Google App Engine, Microsoft Azure, Salesforce. Operating system can be frequently upgraded and developed with PaaS, services can be obtained from diverse sources, and programming can be worked in teams (geographically distributed).

Software-as-a-Service (SaaS), finally, means that users can access various software applications on a pay-per-use basis. As opposed to buying licensed programs, often very expensive. Examples of such services include widely used GMail, or Google Docs.

The longer list will include Storage as a service (STaaS), Security as a service (SECaaS), Data as a service (DaaS), Test environment as a service (TEaaS), Desktop as a service (DaaS), API as a service (APIaaS).

Once you have understood the types of cloud computing, based on location and services, the most important step is to choose the right type of cloud and service, for a specific task with your clients.

Cloud-Native or Just Moving to the Cloud? We Can Help!

Managing cloud infrastructures can be substantially more complex than traditional data infrastructures; however, cloud infrastructures have the potential to become highly optimized, intelligent systems that improve enterprises. Succeeding on the cloud means making the right business decisions and executing the right technological choices. At scale, these challenges get incredibly complex.

At GlobalDots we are proud we can provide some of the most advanced technologies and solutions to help you reduce costs, manage cloud infrastructure and increase security of your public or hybrid clouds.

Achieve Complete Control of Your Cloud Environment with GlobalDots Cloud Management Platform

Moving your business infrastructure to the cloud offers many benefits, compared to having to rely on the traditional, on-premises infrastructure. Efficiency, scalability, security and cost reduction are some of the major benefits that cloud offers organizations.

Still, companies who use the cloud often see their expenses rise over time. This happens because, as business expands, it gets harder and harder for companies to monitor all processes and resources related to cloud-based operations.

Managing cloud infrastructure becomes a set of tasks that require extra time and financial resources. It can be substantially more complex than traditional data infrastructures due to the huge amounts of constantly changing data.

For large enterprises that rely on business data to outperform competition, the only viable approach to analyze the data and optimize their cloud resources is by using data science and machine learning.

GlobalDots helps you quantify, understand, optimize, and automate your infrastructure, to control your data through knowledge. This is achieved through our Cloud Management Platform through which you can monitor and optimize your cloud processes and resources to the smallest detail.

How to Reduce Cloud Costs

If you want to reduce your cloud costs, we can help you with that easily. Our Elastic Compute Cloud solution reduces EC2 costs by 50% – 80% with 100% availability and granted SLAs.

 

Software Defined Operations: Security Guardrails for Your Cloud

Large enterprises usually have many DevOps teams working on several projects simultaneously, in different cloud environments.
The problem with this setup is that it causes friction and slows down development.

With GlobalDots, you can safely enable self-service & direct AWS, Azure and GCP access for all your applications and developers.

GlobalDots helps your cloud team be more efficient, giving it the tooling and automation necessary to manage the complexity of implementing the best practice of a multi-account strategy and allowing SecOps and DevOps teams to focus on higher-value activities.

Developing applications collaboratively creates unique challenges for security teams. Business partners faced with weeks or months of project delays often resort to starting application development offsite with their vendor to “accelerate” the project. Late in the project they discover that key enterprise controls were not considered part of the requirements, causing delays and rework.

GlobalDots allows you to turn this paradigm upside down: Utilizing native cloud services (e.g. the AWS Console and APIs) in conjunction with GlobalDots’ enterprise controls, the system integrator or third parties can be granted access to a cloud development account before the ink is dry on their statement of work.

We help to address the most common cloud challenges faced by large enterprises:

  • Lack of resources/expertise
  • Security
  • Managing cloud spend
  • Compliance
  • Governance/control

All of these issues are easily solved by utilizing our unique platform.

 

Cloud Optimized Routing

If you’re a SaaS provider, you know that sub-second application response time is an important but often unrealized goal.

After all, research has consistently shown that an application response time of over 1 second will cause an interruption in the user’s flow of thought, and a delay of about 10 seconds will result in the abandonment of the task.

The problem with slow application response time usually come from the Internet Backbone problem. The Internet Backbone is made up of many large Network Service Providers that interconnect with each other. These large networks charge Internet Service Providers (ISPs) to transport data packets long distances.

Within the Internet Backbone, all traffic is treated equally, and so ISPs maximize profitability by minimizing the cost of sending traffic. Least cost routing is the process of selecting the path traffic will take along the Internet Backbone based on the lowest cost, not on best performance.

To solve this problem, and to avoid the usual workarounds which aren’t that effective, GlobalDots employs an Internet Overlay Network.

GlobalDots’ Internet Overlay Network leverages the surface area of public cloud providers to continuously monitor the global Internet Backbone to find the fastest routes, avoiding congestion and overcoming the performance problems caused by least cost routing. In the process, it can improve data transfer performance by 10x or more.

GlobalDots is unique in leveraging the surface of the public cloud, across 15+ cloud providers across the globe to provide optimal routing across the Internet Backbone. Other internet overlay providers are trapped in expensive and inflexible private clouds. GlobalDots takes advantage of the scale of public cloud investment in both location and in peering relationships with local ISPs.

Benefits you get from this solution:

  • Fast, seamless content collaboration
  • Dynamic SaaS performance
  • Expansion to new geographies
  • Secure private network

 

Cloud Security

Cloud computing continues to transform the way organizations use, store, and share data, applications, and workloads. It has also introduced a host of new security threats and challenges. With so much data going into the cloud—and into public cloud services in particular—these resources become natural targets for bad actors.

One of the biggest concerns business owners, CTOs and everyone involved with IT decisions in a company have, is related to the security of the cloud infrastructure.

Cloud computing security or, more simply, cloud security refers to a broad set of policies, technologies, and controls deployed to protect data, applications, and the associated infrastructure of cloud computing.

Concerns associated with cloud computing security fall into two broad categories:

  • Security issues faced by cloud providers (organizations providing software-, platform-, or infrastructure-as-a-service via the cloud)
  • Security issues faced by their customers (companies or organizations who host applications or store data on the cloud)

GlobalDots’ Cloud Web Application Firewall (WAF) stops OWASP security threats the moment they happen. We make sure your data is protected from all threats non-stop, and our cybersecurity team acts as an extension of your IT team, working together to stop all possible cyberattacks the moment they happen.

 

DDoS Protection and Mitigation for Cloud Applications

Every day nearly 3000 websites become victims of a DDoS attack. And while many sites are back up and running within hours, the damage to both revenue and customer trust can devastate a business for years.

A distributed denial-of-service (DDoS) attack is a cyber-attack in which an attacker renders a website unavailable to users by attacking it with multiple compromised systems (botnet).

All organizations suffer from DDoS attacks at some point in time, so it’s crucial to have a cloud protection stack in place.
Network DDoS attacks, such as SYN Flood and DNS Amplification attacks, are quickly growing in size. This is why the appropriate capacity for mitigation needs to be provided.

Through partnering with different service providers, we can offer robust CDNs that leverages a global network of strategically positioned servers to provide you the capacity to mitigate even multi-gigabit DDoS attacks.

Our platform provides automated DDoS attack protection at the network layers. These types of attacks are often referred to as Layer 3/4 attacks (aka volumetric attacks) since they effect the lower layers of the OSI Model (Network and Transport). Some examples of types of attacks include:

  • SYN Floods (Spoofed IPs, non-standard TCP flags),
  • UDP Floods,
  • IPSec flood (IKE/ISAMP assoc. attempts),
    IP/ICMP fragmentation,
  • NTP / DNS / SSDP reflection,
  • SMURF,
  • DNS flood

These attacks are generally designed to overwhelm the servers, ultimately resulting in a denial of service for legitimate traffic and disrupting the operation of the network.

 

What About Bad Bots?

Aside from targeted DDoS attacks, your business is in danger of being target by bad bots – automated attacks like click fraud, content and price scraping etc.

Bad bot attacks are on the rise – almost 22% of all web traffic consists of bad bots. Bad bot attacks span across industries, regardless of the size of the company. (If you want to learn more about types, sizes and sophistication of Bad Bots, take a look at our free Bad Bot Report 2018).

Business owners are facing ever increasing threats, that’s why we have created a new approach to combat these threats. Our solution is focused on dynamic behavior profiles of real customers called Behavioral Fingerprinting.

This approach enables GlobalDots to effectively prevent and mitigate 100% of OWASP handbook’s automated attacks, including:

  • Ad fraud
  • CAPTCHA bypass
  • Scraping
  • Spamming
  • Credential cracking
  • Credential stuffing
  • Vulnerability scanning

…And so on.
