Modern business is impossible without reliable IT infrastructure. Ukrainian companies face the choice of deploying their own infrastructure (on-premise), using cloud solutions, or opting for a hybrid approach. Each option has its advantages and disadvantages, and the right choice depends on the business needs, budget, required security level, and scalability.
On-premise infrastructure means that all equipment, software, and data are hosted directly on the company’s premises or on rented spaces in certified data centers, managed by its own IT specialists.
For on-premise infrastructure, there are two main approaches to building:
- Classic Architecture.
- Software-defined architecture and Private Cloud.
Advantages of on-premise:
- Full control: You have complete control over the entire infrastructure, from hardware to data. This is especially important for companies with high requirements for confidentiality and security.
- Security: For many companies, especially those handling confidential data (e.g., financial sector, government agencies), on-premise is considered a safer option, as data does not leave the company’s perimeter.
- Customization: The ability to customize the system to specific needs and integrate it with existing internal systems.
Benefits of on-premise Private Cloud
- Reduced capital expenditures.
- Lower requirements for technical personnel.
- Easy web-scale scalability.
- Fast deployment and migration.
Disadvantages of on-premise with classic architecture approach::
- High capital expenditures.
- The need to maintain a qualified workforce.
- Difficulty in scaling.
- Long implementation time for new solutions.
Cloud solutions (public cloud) involve hosting data and applications on rented virtual resources provided by cloud providers.
Advantages of cloud:
- Flexibility and scalability: Easily scale computing resources up or down according to current needs, making it ideal for businesses with uneven workloads.
- Availability: Access to data and applications from anywhere in the world with an internet connection.
- Reliability and data recovery: Cloud providers offer high reliability, backup, and fast data recovery in case of failure.
- Updates and maintenance: The cloud service provider is responsible for software updates and infrastructure maintenance.
Disadvantages of cloud:
- Dependence on internet stability.
- Potential issues with data localization (important for the public sector).
- Limited control over physical access.
Hybrid infrastructure combines elements of both on-premise and cloud solutions, allowing companies to keep some data and applications locally while moving others to the cloud.
Advantages of the hybrid approach:
- Optimal combination: Allows you to take advantage of both approaches: control over critical data and cloud flexibility for less sensitive applications.
- Phased migration: Enables gradual transition to the cloud, testing different services and adapting to the new architecture.
- Disaster recovery: The hybrid approach may offer better recovery options using the cloud as a backup platform.
When using Software-Defined Architecture and Private Cloud in on-premise infrastructure, the following disadvantages of the hybrid approach are eliminated.
Disadvantages of the hybrid approach:
- Management complexity: Managing a hybrid infrastructure requires greater expertise and more complex integration between on-premise and cloud components.
- Qualified personnel requirements.
- Need for unified monitoring and security.
When choosing the right IT infrastructure, Ukrainian companies should consider the following factors:
- Budget.
- Data securityand confidentiality.
- Scalability.
- IT team competencies.
- Performance requirements.
- Regulatory requirements.
Choosing the optimal IT infrastructure is a balance between flexibility, security, costs, and compliance with the law. AM Integrator Group recommends a comprehensive approach to solving client tasks, conducting IT audits and architecture design, helping to choose the best infrastructure option based on the organization’s requirements, implementing security controls, monitoring, and providing round-the-clock support.
