Modern businesses face ever-increasing demands for speed, flexibility, and reliability in their IT infrastructure. Instead of investing significant capital in acquiring and maintaining their own equipment, companies are increasingly choosing cloud solutions. This transition is not just a trend, but a strategic decision that allows for cost optimization, accelerated innovation, and business continuity.
Cloud migration: a strategic step towards transformation
Migrating IT infrastructure and applications to the cloud is a complex process that requires careful planning and expertise. Depending on business needs, there are different approaches to migration.
- Lift-and-shift (rehost): The simplest option, where virtual machines are moved to the cloud without significant changes. Suitable for rapid migration, but doesn’t always fully leverage cloud benefits.
- Replatform: Involves minor changes to optimize operation in the cloud environment, such as migrating to managed databases.
- Refactor/re-architect: The most in-depth approach, involving redesigning application architecture to maximize the use of cloud capabilities, such as Serverless or containerization (Kubernetes, Docker).
- Retain: Some applications or data may remain in the on-premises data center due to regulatory requirements or specific needs.
- Retire: Outdated or unused systems can be decommissioned.
Choosing the right migration strategy is critical for project success and achieving business objectives.
Cybersecurity in the cloud: protecting data and reputation
With the move to the cloud, security responsibility is shared between the provider and the client. The shared responsibility model is a key concept. The provider ensures the security of the cloud infrastructure, while the client is responsible for the security of data and applications in the cloud.
Modern cloud platforms offer a wide range of cybersecurity tools:
- Identity and access management (IAM, Entra ID).
- Threat protection (Microsoft Defender, CrowdStrike, Trend Micro).
- Security monitoring and event management (SIEM/SOAR, Microsoft Sentinel, Splunk).
- Network perimeter protection (NGFW, WAF, SD-WAN).
- Backup and disaster recovery (DRaaS, Azure Site Recovery, Veeam).
An effective cloud cybersecurity strategy is based on Zero Trust principles and continuous monitoring.
FinOps: optimizing cloud resource costs
One of the biggest advantages of the cloud is the ability to pay only for consumed resources (OPEX instead of CAPEX). However, without proper cost management, cloud bills can quickly escalate. FinOps is an operational model that brings together financial and engineering teams to manage cloud costs. It includes:
- Cost monitoring and analysis: Using tools (Azure Monitor, Datadog) to track resource consumption.
- Resource optimization: Rightsizing (reducing virtual machine sizes), deleting unused resources, utilizing auto-scaling.
- Leveraging discounts: Reserved Instances and Savings Plans for long-term commitments.
- Budget management: Setting limits and alerts for overspending.
Implementing FinOps practices allows businesses to get maximum value from cloud investments, controlling costs and forecasting future expenditures.
How SL Global Service solves this
Since 2009, the SL Global Service team has been helping Ukrainian businesses implement and effectively utilize cloud technologies. SGS engineers apply a vendor-agnostic approach, allowing them to choose the best solutions from a wide range of platforms: Microsoft Azure (including Arc, Stack HCI, VD, Entra ID, Defender, Sentinel, Intune, Site Recovery), AWS (EC2, EKS, RDS, S3, Lambda), Google Cloud (GKE, BigQuery, Cloud Run), and Oracle Cloud (OCI, Autonomous DB).
In the area of cloud migration and architecture, SL Global Service develops tailored strategies, using tools like Azure Site Recovery for seamless migration and subsequent Disaster Recovery. For cybersecurity, we integrate solutions from Cisco Firepower, Fortinet, Palo Alto, Microsoft Defender, CrowdStrike, Trend Micro, and build monitoring systems based on Microsoft Sentinel and Splunk, ensuring comprehensive protection of infrastructure and data. Within FinOps, the SGS team conducts detailed audits of cloud expenditures, applying rightsizing and resource optimization practices, which allows clients to reduce costs by 20-40% without sacrificing performance. For VDI and cloud workspaces, Azure Virtual Desktop, Windows 365, and Citrix DaaS are implemented, providing flexibility and accessibility of work environments. Our managed cloud 24/7 services cover monitoring using Prometheus, Grafana, Datadog, and Azure Monitor, as well as infrastructure and licensing management (Microsoft CSP/EA, VMware VPP, Veeam VCSP). For automating infrastructure deployment and management, SGS engineers use DevOps tools: Terraform, Ansible, Pulumi, GitHub Actions, and Azure DevOps. A typical result of collaboration is increased fault tolerance, reduced operational costs, and accelerated time-to-market for new products.
Transitioning to cloud technologies is an inevitable stage of development for any business aiming to remain competitive. Careful planning, choosing the right migration strategy, ensuring reliable data protection, and continuous cost optimization are key to successful implementation. Consult experts to develop a customized transformation plan and get the maximum return on your cloud investments.
