Public Cloud Solutions in Cloud Infrastructure

Public Cloud Solution

What is a Public Cloud Solution?

Struggling with IT infrastructure limitations? Public cloud solutions offer a game-changing approach, delivering scalable and cost-effective computing resources on-demand. But what exactly is a public cloud?

  • Definition: Public cloud as a model for delivering cloud computing resources over the public internet.
    Imagine a virtual IT department accessible from anywhere with an internet connection. That’s the essence of a public cloud. Providers like AWS, Azure, and GCP offer a vast pool of resources – servers, storage, databases, networking, software, and even analytics tools – all accessible over the public internet.

    These resources are shared among multiple users, but your data remains secure and isolated. Need more processing power for a sudden surge in traffic? No sweat! Public cloud lets you scale resources up or down in minutes, ensuring you only pay for what you use.

    Consider your specific needs (compute power, storage requirements) and how the cloud scales to meet your growth. Security is paramount, so prioritise providers with strong compliance certifications. Don’t forget to factor in pricing models and how seamlessly the cloud integrates with your existing IT setup.

Drowning in Server Management? Scale Up with Secure Cloud Infrastructure

Struggling with outdated hardware, rising IT costs, and limited scalability? Our secure cloud infrastructure services free you from hardware headaches, reduce costs, and provide on-demand resources to fuel your growth.

  • Shared Infrastructure: Resources are pooled and shared among multiple users.
    Imagine a bustling co-working space – a single location with resources like desks, printers, and internet access, all shared by multiple businesses. That’s the basic idea behind shared infrastructure in public cloud solutions.

    Providers like AWS, Azure, and GCP maintain massive data centers packed with servers, storage, and networking equipment. These resources are then divided and shared among multiple users, offering a cost-effective way to access the computing power you need.

    While resources are shared, security remains a top priority. Public cloud providers secure the underlying infrastructure. However, you’re responsible for securing your data and applications. Encryption is key, so encrypt your data at rest and in transit. Implement strong access controls and consistently monitor your cloud activity for any suspicious behavior.

  • On-Demand Access: Users can self-service provision and scale resources as needed.
    Consider that a project calls for a new server, but having to wait weeks for procurement and setup. That’s the frustration of traditional IT. Public cloud solutions offer a refreshing alternative: self-service provisioning. With a few clicks through an intuitive interface, you can provision the resources you need – servers, storage, databases –  instantly.

    Need more processing power for a marketing campaign? No problem! Scale your resources up in minutes. Finished with the project? Scale back down to avoid unnecessary costs. You’re in complete control, with on-demand access to the IT resources you need, when you need them.

    On-demand provisioning lets you deploy applications and infrastructure faster than ever before. This agility fuels innovation and helps you seize new business opportunities.

    Self-service provisioning frees your IT team from time-consuming tasks like server setup and configuration. They can focus on strategic initiatives that drive business value.

  • Pay-as-you-Go Model: Users only pay for the resources they consume.
    Think back to the days of unlimited data plans that ended with a hefty bill shock. Traditional IT can be similar – you invest in hardware and software, but often a significant portion goes unused.

    Public cloud with its pay-as-you-go model eliminates this waste. You only pay for the resources you actually consume – servers, storage, databases, and more. Need extra processing power for a short-term project? The cloud lets you scale up, then scale back down without any unnecessary costs.

    Pay-as-you-go puts you in control of your IT spending. No more upfront capital expenditure on hardware or software licenses. You only pay for what you use, keeping your IT budget flexible and efficient.

    The pay-as-you-go model is ideal for businesses with fluctuating resource needs. You can scale your IT infrastructure up or down as your business grows, without significant upfront investments.

Benefits of Public Cloud Solutions for Cloud Infrastructure

Public cloud computing, which provides an adaptable and affordable method of managing your IT infrastructure, is sweeping the business community. But why is it specifically so advantageous? Now let us explore the main benefits that public cloud solutions offer for your cloud architecture.

Security Considerations for Public Cloud Solutions

Data Encryption:
Data encryption acts as its bodyguard, transforming it into an unreadable jumble using powerful algorithms. Only authorized users with the decryption key can unlock the true meaning of your data, ensuring its confidentiality.

Data encryption safeguards your information in two critical ways:

  • Data at Rest: Encryption scrambles your data while it’s stored in the cloud, like locking your treasure chest shut before placing it in the vault.
  • Data in Transit: Encryption protects your data as it travels between your systems and the cloud, like having an armored carriage guarded by knights to deliver your valuables.

Identity and Access Management (IAM):
IAM acts as your gatekeeper, ensuring only authorized individuals with the right credentials can enter specific areas. IAM lets you define who can access your cloud resources (like compute instances, storage buckets, and databases) and what actions they can perform (like read, write, or delete).

Think of it like issuing special permits for specific areas of your city, ensuring only authorized individuals can access sensitive locations. IAM empowers you to create detailed policies that define access permissions in your cloud kingdom.

Monitoring and Logging:
Monitoring and logging act as your tireless watchtower sentinels, constantly scanning for suspicious activity. Monitoring systems track resource usage and performance metrics, while logging captures detailed records of events happening within your cloud environment. By analyzing this data, you can identify potential threats before they escalate into major breaches.


Public cloud security can feel like a gamble, but with the right provider, your data is in Fort Knox! Here at Portman Tech Solutions, we prioritise ironclad security:
