The speed of change in the business environment demands maximum flexibility and scalability from companies’ IT infrastructure. Traditional on-premises solutions often fail to provide the necessary level of adaptability, leading to delays in launching new products, increased operational costs, and downtime risks. This is why cloud technologies, with their pay-as-you-go architecture and global availability, have become a key tool for ensuring competitiveness and sustainable business development, especially in the face of constant challenges.
Cloud-first strategy: why it matters
A Cloud-first strategy prioritizes the use of cloud solutions for new projects and the modernization of existing systems. This is not just about data migration, but a shift in the approach to IT management, allowing companies to focus on their core business while delegating complex infrastructure support tasks to cloud providers. This approach offers a number of advantages:
- Rapid deployment: New services and applications can be launched in minutes or hours, rather than weeks or months.
- Scalability: Resources automatically scale according to current needs, avoiding redundant investments or capacity shortages.
- Reduced CAPEX: Transition from capital expenditures (CAPEX) on infrastructure to operational expenditures (OPEX) for cloud services.
- Global accessibility: Access to data and applications from anywhere in the world, which is critical for remote work and international expansion.
Cybersecurity in the cloud: protecting data and systems
Despite common myths, the cloud can be more secure than traditional on-premises solutions if configured correctly. Leading cloud providers invest billions of dollars in physical data center security, network protection, and the development of cybersecurity tools. However, the responsibility for data protection is shared: the provider is responsible for the security of the “cloud,” and the client is responsible for security “in the cloud” (Shared Responsibility Model). This includes:
- Data protection: Encryption of data at rest and in transit, access control.
- Threat protection: Use of Next-Generation Firewalls (NGFW), Intrusion Detection/Prevention Systems (IDS/IPS), EDR solutions.
- Identity and access management: Multi-factor authentication (MFA), Privileged Access Management (PAM), and Zero Trust models.
- Monitoring and response: SIEM/SOAR systems for continuous monitoring of security events and automated incident response.
| Security aspect | On-premises | Cloud |
|---|---|---|
| Physical security | Company responsibility | Provider responsibility |
| Network security | Company responsibility | Shared responsibility |
| Data protection | Company responsibility | Shared responsibility |
| Software updates | Manual/automated | Automated by provider |
| Compliance | Harder to achieve | Built-in support |
Cost optimization (FinOps) in cloud environments
While the cloud offers significant advantages, uncontrolled resource usage can lead to unexpected costs. FinOps is an operational practice that brings together financial and engineering teams to effectively manage costs in cloud environments. Key FinOps principles include:
- Transparency: A clear understanding of who is spending cloud resources and on what.
- Optimization: Continuously seeking ways to reduce costs without compromising performance and reliability. This includes rightsizing instances, using Reserved Instances/Savings Plans, and Spot Instances.
- Automation: Implementing tools for automated resource and cost management.
- Culture: Fostering collaboration between teams to make informed decisions about cloud resource utilization.
How SL Global Service solves this
The SL Global Service team, as a vendor-agnostic cloud integrator, offers a comprehensive approach to implementing and managing cloud technologies for Ukrainian businesses. SGS engineers help companies transition to a Cloud-first strategy, leveraging a wide range of technologies and services:
- Cloud migration and architecture: SGS engineers develop optimal cloud architectures and implement the migration of existing infrastructures to Microsoft Azure (Azure Arc, Azure Stack HCI, Azure Virtual Desktop), AWS (EC2, EKS, RDS, S3), and Google Cloud (GKE, BigQuery) platforms. They use a Lift-and-shift approach or complete application modernization with containerization (Docker, Kubernetes) and Serverless computing (AWS Lambda, Google Cloud Run).
- Cybersecurity: To ensure a high level of protection, solutions from Cisco Firepower, Fortinet, Palo Alto, Microsoft Defender, CrowdStrike, Trend Micro, and Trellix are used. Microsoft Sentinel and Splunk are implemented for centralized security monitoring and incident response, as well as Duo for MFA and Zero Trust architectures.
- Managed Cloud 24/7: The SGS team provides 24/7 monitoring (Prometheus, Grafana, Datadog, Azure Monitor) and management of cloud infrastructure, ensuring High Availability and performance.
- DevOps and CI/CD: Application of Terraform, Ansible, Pulumi, GitHub Actions, and Azure DevOps for automating infrastructure deployment (IaC) and CI/CD pipelines, accelerating product releases.
- FinOps: SGS engineers implement FinOps practices, using Azure Cost Management tools and analytics for optimizing cloud costs, including rightsizing and Reserved Instances management.
- VDI and Microsoft 365: Deployment of Azure Virtual Desktop, Citrix DaaS, or Windows 365 for organizing secure and flexible cloud workspaces, as well as full implementation and support for Microsoft 365, Teams, SharePoint, and Exchange Online.
- Backup/DR: To ensure business continuity, solutions from Veeam, Commvault, Acronis, Zerto, and Azure Site Recovery are used, guaranteeing low RPO/RTO.
The result of this collaboration is a stable, secure, and cost-effective IT infrastructure that fully meets the needs of modern business and allows for unlimited scalability.
Transitioning to cloud technologies is not just a technical solution, but a strategic step to ensure the resilience and growth of your business. It is important not just to migrate data, but to carefully plan the architecture, ensure an appropriate level of cybersecurity, and effectively manage costs. Start with an IT audit to determine the optimal transition and modernization strategy.
