      Secure Cloud App Development

      Security and compliance are non-negotiable for enterprises. Off-the-shelf Cloud apps may not always meet your needs – that’s why we design and deliver enterprise-grade custom apps with security built in from the start. From data handling to permissions and auditability, your compliance standards remain fully intact.

Our consultants work with you to minimize downtime, mitigate risks, and manage costs, so you don’t just migrate – you upgrade strategically.

    Frequently Asked Questions

    What does Atlassian Data Center end of life mean and when is it?

    Atlassian will end of life impacted Data Center products on March 28, 2029 (23:59 PST), with a phased wind-down starting March 30, 2026. Existing subscriptions and associated Marketplace apps will expire at EOL and become read-only. Planning early reduces risk and ensures capacity with trusted partners.

    Which Data Center products are affected?

    Jira Software DC, Jira Service Management DC, Confluence DC, Bamboo DC, Crowd DC, DC mobile apps, and DC Marketplace apps are included. Bitbucket DC is excluded and follows a Hybrid License path.

    How does Seibert help if my DC app isn’t available on Cloud?

    We rebuild your missing functionality as a Cloud-ready custom app, aligned with your business requirements and governance needs.

    Our compliance needs exceed what standard Cloud apps offer. Can you build secure alternatives?

    Yes. We create enterprise-grade Cloud apps that meet your security, compliance, and audit requirements.

    Can you migrate our custom implementations and workflows to Cloud?

    Absolutely. We analyze your unique workflows, integrations, and data models, then re-implement them in Cloud with a cutover plan that minimizes downtime.

    What about DC scripts and automations?

    We assess your scripts, evaluate Cloud feasibility, and re-create them with modern APIs or custom apps to ensure continuity and maintainability.

    Do you offer training and enablement for our teams?

    Yes. We provide workshops and training tailored to admins, developers, and stakeholders on Cloud architecture, Forge, Rovo, testing, and operations.

    Why act early if EOL is still years away?

    Custom development and complex migrations take time, and partner capacity will tighten as the deadline approaches. Early action secures resources and enables phased rollouts.

    What’s your engagement model?

    We begin with an assessment and roadmap, then work in milestones — design, build, test, rollout — with clear SLAs and governance reporting.

    How do we get started?

    Book a consultation and we’ll review your DC landscape as well as identify custom development needs for Cloud. Afterwards we’ll propose a roadmap with secured capacity.

    Ready to Start Your Cloud Journey?

    Let’s make sure your transition from DC to Cloud is not just smooth – but a step up.
