The Rise of Cloud Hosting
To fully appreciate the significance of IBM iSeries cloud hosting, it’s essential to understand the broader context of cloud hosting and its impact on the IT landscape. Cloud hosting refers to the practice of using remote servers hosted on the internet to store, manage, and process data, rather than using a local server or personal computer.
Types of Cloud Hosting:
- Public Cloud: Services are provided over a network that’s open for public use. This is the most common and cost-effective form of cloud hosting.
- Private Cloud: The cloud infrastructure is operated solely for a single organization. It can be managed internally or by a third party.
- Hybrid Cloud: A combination of public and private clouds, allowing data and applications to be shared between them.
The rise of cloud hosting has been driven by several key benefits:
- Scalability: Cloud resources can be easily scaled up or down based on demand.
- Cost-Effectiveness: Pay-as-you-go models reduce upfront capital expenditure.
- Flexibility: Access to resources and applications from anywhere with an internet connection.
- Disaster Recovery: Improved backup and recovery capabilities.
- Automatic Updates: Cloud providers handle system maintenance and updates.
These advantages have led to widespread adoption of cloud hosting across industries. According to Gartner, the worldwide public cloud services market is forecast to grow 21.7% in 2022 to total $482 billion, up from $396 billion in 2021. This trend underscores the increasing reliance on cloud technologies for business operations.
As organizations recognize these benefits, there’s a growing interest in bringing legacy systems like IBM iSeries into the cloud environment. This convergence of traditional systems and cloud technology is where IBM iSeries cloud hosting shines, offering a unique solution that combines the reliability of iSeries with the flexibility of the cloud.

IBM iSeries cloud hosting represents a paradigm shift in how businesses leverage their legacy systems. It’s the fusion of the robust, reliable IBM iSeries platform with the flexibility and scalability of cloud computing. This innovative approach allows organizations to maintain their critical iSeries applications while taking advantage of cloud benefits.
What is IBM iSeries Cloud Hosting?
IBM iSeries cloud hosting involves migrating IBM i (AS/400) systems and applications to a cloud environment. This can be achieved through various models, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or even Software as a Service (SaaS) for specific iSeries applications. The goal is to provide the same level of performance and reliability that iSeries users expect, but with the added advantages of cloud technology.
How Does It Differ from Traditional On-Premises Hosting?
The key differences between IBM iSeries cloud hosting and traditional on-premises hosting are:
| Aspect | Traditional On-Premises | IBM iSeries Cloud Hosting |
|---|---|---|
| Infrastructure Management | Managed in-house | Managed by cloud provider |
| Scalability | Limited by physical hardware | Easily scalable on-demand |
| Cost Model | Capital expenditure (CapEx) | Operational expenditure (OpEx) |
| Accessibility | Often limited to on-site access | Accessible from anywhere with internet |
| Disaster Recovery | Requires separate DR site | Built-in redundancy and DR options |
Key Advantages of Moving IBM iSeries to the Cloud
- Scalability: Cloud hosting allows businesses to scale their iSeries resources up or down based on demand. This flexibility is particularly valuable for businesses with seasonal fluctuations or rapid growth.
- Cost-effectiveness: By moving to a cloud model, organizations can shift from a capital expenditure (CapEx) model to an operational expenditure (OpEx) model. This change can result in significant cost savings, as businesses only pay for the resources they use.
- Improved Disaster Recovery and Business Continuity: Cloud providers offer robust disaster recovery solutions, often with multiple data centers across different geographical locations. This setup ensures better business continuity compared to traditional on-premises solutions.
- Enhanced Security: While security is often cited as a concern for cloud migration, reputable cloud providers invest heavily in security measures. They often have more resources dedicated to security than an average organization can afford for its on-premises systems.
- Easier Maintenance and Updates: Cloud providers handle system maintenance, updates, and patches, freeing up internal IT resources to focus on more strategic initiatives.
Case Study: Manufacturing Company Embraces IBM iSeries Cloud Hosting
A mid-sized manufacturing company, relying heavily on IBM iSeries for its ERP system, faced challenges with aging hardware and increasing maintenance costs. By adopting IBM iSeries cloud hosting, they achieved:
- 40% reduction in IT infrastructure costs
