Cloud Migration
Cloud migration allows companies to move their digital assets, services, databases, IT resources, and applications partially or wholly into the cloud. Cloud migration allows for moving from one cloud to another.
Sela has deep expertise is in all forms of migrations: whether its on-prem to cloud or cloud to cloud, and across all major cloud providers.
Migrate and Modernize Your Workloads
Migrating to the cloud can unlock huge value for your organization. But embarking on the journey without the necessary skillset can result in fragmented infrastructure, operational stagnation, and a dysfunctional technology organization. Our team has deep experience navigating the procedural, organizational, and technical challenges surrounding successful cloud migrations.
Our team offers a comprehensive range of expertise that spans from hardware to distributed cloud-native software and applications. We have a deep understanding of physical, hybrid-cloud, and cloud networks.
Our experience extends to both legacy enterprise software methodologies and tooling as well as modern cutting-edge methodologies and tooling. We bring automation expertise to every migration, and our approach is built around infrastructure-as-code, system observability, and simplifying engineering operations across your teams.
We believe that complexity endangers any cloud migration. We, therefore, propose architectures are simple and adhere to well-defined industry best practices rather than re-inventing the wheel.
Scoping migrations in phases and breaking down systems into workloads enables you to ensure that you attain incremental success along the way. Sometimes complexity is unavoidable, but we make it our mission to reduce complexity and unknowns as much as possible during migration preparation.
While we are comfortable with rehosting software in the cloud with physical- to-virtual or virtual-to-virtual lift-and-shifts, we prefer to containerize applications where possible and deploy them to cloud-native container platforms to simplify operations.
Our team has deep expertise with cloud- container platforms like AWS's EKS and ECS, GCP's GKE, and Azure's AKS. We understand the complexities of deploying and managing containerized applications at scale, and we can help you develop and implement container strategies that meet your specific business needs.
We make a point of understanding your teams' needs and your organization's bottlenecks and are committed to ensuring your engineers will be able to operate migrated cloud environments.
We will often embed engineers across your organization to this effect. As we learn about your organization, we adapt to your specific needs and goals. When you are looking to replace legacy components, we can also help you refactor these to support cloud-native patterns.
Our team is laser-focused on security and can help remediate technical aspects of FedRAMP, HIPAA, HITRUST, SOC-2, and other compliance frameworks.
Our security- first approach involves deep collaboration with your security team to ensure that all security requirements are met.
Cloud Migration FAQs
As a Premier partner of AWS, Azure, Google Cloud and other cloud providers, Sela specialized in all forms of migrations. Reach out to consult with our migration experts.
Cloud migration is the process of moving digital assets—such as data, workloads, IT resources, and applications—from on-premises infrastructure to a cloud platform, or from one cloud to another. Organizations migrate to the cloud to increase scalability, improve security, reduce infrastructure maintenance, and adopt modern technologies like AI and automated analytics.
Migrating from on-premises to the cloud involves four primary phases: discovery and workload assessment, cloud architecture design, migration execution (using strategies like rehosting or refactoring), and post-migration optimization. Sela guides organizations through this entire lifecycle, setting up parallel testing environments to ensure zero data loss and minimal operational downtime.
Sela provides end-to-end cloud migration and modernization services across AWS, Microsoft Azure, and Google Cloud Platform (GCP). Sela's services include pre-migration infrastructure assessment, cloud architecture design, application rehosting (lift-and-shift), replatforming, cloud-native refactoring, database migration, automated security compliance (SOC 2, HIPAA, ISO 27001), and post-migration FinOps optimization.
Sela mitigates operational downtime by using phased, wave-based migration strategies alongside automated data replication tools. Prior to cutover, Sela establishes parallel sandbox environments to perform validation testing, data synchronization, and automated rollback readiness checks to ensure business continuity.
Sela supports all core cloud migration strategies tailored to your workloads:
Rehosting ("Lift and Shift"): Rapidly moving existing workloads to the cloud with minimal architectural changes.
Replatforming: Modernizing specific OS, database, or middleware layers without changing core application code.
Refactoring / Modernization: Re-architecting legacy applications into microservices and containerized environments (Kubernetes/Serverless) for full cloud-native performance.
Repurchasing, Retiring, & Retaining: Transitioning to SaaS, decommissioning legacy software, or maintaining hybrid workloads on-premises for strict compliance requirements.
Migration timelines depend on application complexity, data volume, and interdependencies:
Simple applications or single workloads: 4 to 8 weeks.
Large databases and complex ERP systems: 3 to 6 months.
Enterprise-wide cloud transformations: 6+ months in phased deployment waves.
Sela embeds security controls into every phase using a security-first approach. We enforce end-to-end encryption for data in transit and at rest, implement Zero Trust Identity & Access Management (IAM), automate vulnerability scanning, and align infrastructure with regulatory frameworks including SOC 2, ISO 27001, HIPAA, and GDPR.
Yes. Sela integrates FinOps best practices into the migration process. Post-migration services include compute and storage rightsizing, auto-scaling configuration, setting up real-time cost anomaly alerts, eliminating unutilized resources, and configuring reserved instances or savings plans to reduce cloud expenditure.
Yes. Sela designs unified hybrid and multi-cloud architectures that allow organizations to securely bridge on-premises data centers with AWS, Azure, and GCP, providing cross-cloud orchestration, unified management, and low-latency networking.
