Public vs Private vs Hybrid Cloud for your Business

1024 528 Parkar Digital

From an innovative storage solutions to hosting robust applications, cloud has become the operating standard for the enterprises. The question is no longer whether you want to trust your operations to a cloud architecture but which type of cloud infrastructure is best for your business: public, private, or a hybrid mixture of both.

To select the right cloud deployment method, you need to map out basic applications i.e. web service delivery to the cloud and compare on the benefits such as cost, reliability, flexibility and computing power.

In this blog, we will discuss the use-cases and compare on all the major criteria to help your business make the right decision.

Public cloud services

A public cloud solution is what most people think of when considering cloud architecture. With this model, a third party provides storage, application hosting, and other resources to individual and organizational users via the internet.

Computing power

Because public clouds include shared resources, companies are able to leverage their providers’ high-capacity computing power and bandwidth capabilities. It also means they can scale up capacity during peak times.

Security

The sharing inherent in public clouds can lead to security and privacy concerns because users have no control over how their providers implement cloud security.

Cost and maintenance

Public clouds are the least expensive to set up because the provider pays for the hardware, hosting, and bandwidth in a pay-for-use model. The provider is also responsible for managing these resources.

Integrity

Public cloud users have no control over how their providers maintain the integrity of their data. Because of the shared storage resources, any corruption event can affect all computers sharing the database. Therefore, they need to put your trust in their providers, so choose wisely.

Availability across different regions

Public cloud users can access resources from anywhere with a computing device and access to the internet.

Public Cloud Use-cases

Public cloud models are best-suited for IT executives in small- to medium-sized businesses in industries without heavy regulations. They’re appropriate for standard enterprise applications many users access, software development processes that require collaboration, software as a service (SaaS) solutions, and other applications that don’t involve highly sensitive data.

Private cloud services

In a private cloud infrastructure, a private network hosts services and infrastructure, often for a single enterprise. Access is restricted to specified clients rather than publicly accessible. Private cloud services are similar to on-premises data centers users access through virtualization technologies. The organization owns and manages the infrastructure or contracts these services through a third-party vendor under their direction.

Computing power

Computing, storage, and networking resources are dedicated to a single organization, so IT leaders have control over resources. However, they have access to a limited supply matched to their demand. They are not leveraging the power of shared resources.

Security

Private clouds offer the highest levels of security because access is limited to the organization’s private network, and they have more specific security controls than public clouds.

Cost and maintenance

Private clouds are less cost-efficient. Users pay for resources dedicated solely to their network users, and they have to pay to keep them updated. They or their private cloud providers are responsible setting up and maintaining their private cloud infrastructures.

Integrity

Private clouds share databases only within each infrastructure’s private network, so less chance of data corruption exists. When a corruption event occurs, it stays within the organization.

Availability across different regions

Although each private cloud is dedicated to one organization, each organization can distribute information across many company locations via the network. Private cloud services provide high availability and redundancy because organizations can reallocate all resources in the event of a failure.

Private Cloud Use-cases

Private cloud services are best-suited to businesses that revolve around proprietary data or those that process and store private data or carry out sensitive tasks. Good candidates include financial institutions, eCommerce companies, and health care providers. Internal business operations are often run on private clouds.

Hybrid cloud services

The above parameters provide guidelines for IT leaders to choose which type of cloud solution is their best option.

However, choosing a public over private cloud solution or vice-versa often doesn’t make sense, especially for those whose businesses are or are becoming more complex.

IT decision-makers may want to take advantage of public cloud architecture efficiency and cost savings for standard enterprise applications that many users access. On the other hand, they might also own a lot of confidential information that requires more secure handling.

In these situations, hybrid solutions may be the answer. A hybrid solution mixes and matches services — often from different providers — to support necessary applications, data, and infrastructure in the most cost-effective and efficient way possible in accordance with company structure and business requirements.

According to Gartner, most of the medium and large organizations are moving towards a Hybrid Cloud or Multi-Cloud strategy that is something to consider for any business which is dealing with complex data and needs high availability across all regions.

For applications such as Netflix, where high speed and high availability are critical, a hybrid solution can ensure high availability and fast content delivery — but also provide high security for customers’ private data.

Many believe choosing among hybrid, public, and private cloud services is basically a trade-off between cost efficiency and security.

However, if you exercise due diligence and implement security best practices, your data, applications, and computing environment can be safe and secure no matter which solution you choose, leaving you free to select the best model based on your organizational infrastructure and operational priorities.

DevOps: Unify Your Software Development and Operations Teams

1600 1067 Parkar Digital

You’re involved in software development, but are you stuck in the past? If your development and operations professionals use older models, they likely work in two separate teams with little integration or interaction until development hands projects off to operations. Without constant communication, your operations teams test products and send changes back to development teams to incorporate. That’s a lot of information to pass back and forth — not to mention a lot of rework. It’s not only difficult to estimate time and costs while utilizing this method but goals and technologies can also change during the project cycle.

If you haven’t heard of DevOps, your product development process likely sounds a lot like the example above — and it might be costing you more time and frustration than necessary. But other than being a software development buzzword, do you know what it is and what it means — or could mean — to your project management processes? If not, it’s time you found out.

What is DevOps?

DevOps, a portmanteau of development and operations, is an organizational structure and culture with a continuous development and testing cycle. That means a lot less back and forth between development and operations teams as well as less rework, making for a quicker time to market. In fact, DevOps projects allow developers to produce fully functional, high-quality final products more quickly and cost-efficiently than other development processes. This is made possible through the DevOps continuous integration, continuous delivery (CI/CD) project management model that makes extensive use of automation.

CI/CD practices

In a DevOps organization, development team members work closely with operations personnel throughout project development from the initial build through release. CI allows two or more different developers to write code, which they continually integrate with code from other developers — at least daily — in an area known as the source repository. With the code in a single location, developers can then test it. Code will behave differently in different environments, so if developers continually test in different environments, they can be fairly certain it will perform as expected in most situations. Developers usually use a tool such as a CI server for the coding, integration, and testing so each piece of code and all changes are implemented, tested, and verified before moving on.

This leads to the CD component of CI/CD. Through close collaboration between the development and operations teams, developers can discover and correct problems earlier in the development process. In a CD environment, developers not only integrate and test code after they make changes but they also test in environments similar to production. This helps ensure their code works as intended in the real world and reduces product failures and rollbacks.

DevOps model advantages

DevOps streamlines the development process through such cross-team collaboration and a circular approach. Instead of development team members fighting to release new features and operations team members worrying about new code stability, both teams work together to deliver new features and stabilize code at the same time. Through a shared code base, continuous integration, and constant testing, they can discover problems and fix them earlier in the development process.

In non-DevOps environments, developers write all code then hand it off to the operations team in a slow, cumbersome linear process that often results in building new features on top of poor or untested base code. In some cases, development teams need to scrap entire projects and restart using alternative development methods.

With DevOps, you can achieve benefits such as:

  • Shorter time to market
  • Greater agility in responding to problems or changing specifications
  • More frequent product update delivery
  • Greater collaboration across your development and operations teams, resulting in better end products with greater usability
  • Fewer deployment problems and failures
  • Greater alignment between IT and other areas of your business

Some benefits are intangible, such as greater collaboration, communication, and trust among team your members, which can lead to more brainstorming and innovation. Working within the DevOps model, your development and operations team members can cultivate more confidence, empowerment, and job satisfaction.

Fast forward into the future! If you’re ready to help those in your organization experience the benefits of a DevOps life cycle management environment, it’s important you work with an expert team to coordinate the process and reap the most value.

Avoid Service Failures and Customer Complaints with Proactive Monitoring

900 600 Parkar Digital

Nothing kills business productivity like an IT system malfunction, but it’s surprising how many company leaders neglect to monitor their systems until something happens. The price of proactively monitoring company systems is typically a lot less than the cost of reprocessing data or rolling back production in the event of a malfunction. If you and your IT department members could use some help understanding proactive monitoring and its importance for predicting service failures, here’s what you should know.

Predicting service failures

Proactive monitoring helps Parkar Digital clients continually understand how well their services are performing. This allows them to identify potential points of concern rather than investigating why systems malfunctioned after the fact. Proactive monitoring tracks system health 24/7.

In a traditional IT environment, those who manage monitoring may not have visibility beyond infrastructure. Unfortunately, that limited scope is not enough. You need to monitor:

  • Infrastructure — This is the most basic type of monitoring and includes components such as servers, load balancers, and storage devices.
  • Platforms — The platforms on which applications are built also require monitoring as do the third-party tools associated with them. These include databases and data repositories, big data platforms, search engines, as well as business intelligence (BI) and reporting tools, among others.
  • Applications — Application-level monitoring can uncover bugs and incompatibilities in test environments, but IT staff members also need to monitor continuously after deploying applications. Building application programming interfaces (APIs) into application codes during development can make application-level monitoring easier.
  • Business — Business-level monitoring includes checking whether the software in place meets company leaders’ established goals.
  • End users — Monitoring how end users experience application performance is the final level of monitoring, but it’s not possible to analyze in the same environment where applications are running. IT professionals can use software as a service (SaaS) tools to monitor and send alerts when applications fail or perform poorly.

Full proactive monitoring allows Parkar clients to take an offensive stance rather than react to issues already causing problems.

Healthy systems equal happy customers

Customers rely heavily on their experiences with your company services in developing their overall opinions of your business. If a system failure or performance issue were to cloud that experience, it could hurt your company’s reputation.

To preserve a good customer experience and positive business reputation, you need to be able to predict and remedy system failures or poor performance issues before customers notice. Customers rely on and expect your systems to be available and perform well. Underperforming systems are not only costly to fix but can impact business in addition to your end users’ opinions. A reliable proactive monitoring solution from Parkar that detects problems early and alerts you accordingly can reduce the chances that service failures will impact your customers.

Peak performance

Proactive monitoring helps ensure peak performance for IT systems. The tools experts at Parkar use to monitor their clients’ system health — including computers, networks, applications, datacenters, and security — can also benchmark performance and proactively predict when they should schedule upgrades. They can use monitoring to check server event logs, backup status, and antivirus updates. Parkar professionals can also detect client security vulnerabilities before breaches occur by proactively monitoring company systems. This gives them the opportunity to thwart breaches that could potentially compromise company computers and networks before customers even have the chance to notice.

Overall, proactive monitoring can provide greater system reliability, help avoid downtime, increase productivity, reduce security vulnerabilities, and, ultimately, reduce IT support expenses. Don’t wait until disaster strikes to commit to a proactive solution.
