Solution scenario

A reference architecture for public institutions

In a public sector workload the load usually follows office hours, and the real question is traceability rather than capacity. This page shows how a single controlled entry, nested boundaries and document retention are set up.

Primary decision
Where the boundary is drawn and keeping a single entry
Data layer
The document archive in object storage, its copy in a vault
Boundary
Conformance with legislation is the institution’s assessment

Overview

What is the first architectural question in a public sector workload?

In this scenario the first question is the boundary, not capacity. The system opens outward through a single controlled point; the application front end, the document archive and the backup vault all stay behind it inside two nested boundary frames. Every inbound request passes through the same router and the access record is kept there, because who reached what and when matters as much as the system’s output. The second decision is that the data layer is document-oriented: application attachments and output documents accumulate in object storage, and the retention period is set by institutional policy and the legislation the institution is subject to. The third is the predictability of the load; application periods follow a calendar, so capacity is planned and preparation is preferred over automatic growth. Topics such as KVKK and KEP are requirements of this scenario.

Typical workload profile

Predictable load, accumulating documents

Load concentrates in office hours and application periods follow a calendar, so capacity is prepared in advance rather than auto-scaled. Document volume, by contrast, never falls, because the archive is not deleted. The main tension in the profile lies between predictable traffic and continuously growing retention.

Traffic pattern

Tied to office hours, with a scheduled application peak

  • Load concentrates in office hours
  • Application periods follow a calendar
  • Capacity is prepared, not auto-scaled

Data volume

Documents accumulate rather than being deleted

  • Application attachments in object storage
  • Retention set by institutional policy
  • Backup copy in a separate vault

Latency and compliance

Traceability comes ahead of latency

  • A single controlled entry point
  • Access record at the boundary
  • KVKK and KEP as scenario requirements

KVKK and KEP are treated as the institution’s architecture requirements. Certificates are issued to vMind Information Technologies.

Reference architecture

Two nested frames, one crossing point

The diagram reads along the spatial axis: an outer institutional network boundary, a managed project boundary inside it and a single path crossing both. The client stands furthest out, the router waits at the boundary, and the application and archive stay innermost. The access record is a side component — not part of the flow but its trace.

Nested boundary frames with a single controlled entryThe internal client stands furthest out and passes through the single controlled entry. That entry sits inside the institutional network boundary, which in turn contains the managed project boundary. Inside the project boundary are the application front end, the document archive and the backup vault. The access record attaches to the application front end with a dashed link.Institutional network boundaryManaged project boundaryInternal clientInbound requestSingle controlled entryRouterApplication front endComputeDocument archiveObject StorageBackup vaultBackupAccess recordAudit trailsingle pathretentionrecord
The institutional network and the project boundary are two nested frames. Every request passes through one controlled entry.

PortvMind Cloud services used

Boundary, application, archive and vault

The router owns the boundary and access rules, Compute the application front end, Object Storage the document archive, and Backup the archive’s copy in a separate vault. What distinguishes this combination is that storage is document-oriented rather than transactional; the data is kept to be retained and retrieved, not continuously read.

  1. Router

    The single controlled point facing outward and the boundary where access rules are defined.

  2. Compute

    The application front end runs on capacity planned around office hours.

  3. Object Storage

    Application attachments and output documents accumulate here as an archive.

  4. Backup

    The archive’s copy in a separate vault and its retention calendar are set up with this service.

Evaluation criteria

Entry, boundary, retention and legislation

The table covers the entry point, the institutional and project boundaries, archive retention and its copy, and legislative topics. KVKK and KEP enter the architecture as the institution’s requirements. The entry point, boundary layer and archive copy are set at setup.

  • What Is Cloud Backup? How to Plan Enterprise Backups

    Cloud backup stores scheduled copies of your servers, volumes and application data. With PortvMind Cloud Backup you create, track and restore those copies from the panel. A snapshot is for a fast rollback; lasting protection comes from Backup.

  • Object Storage Architecture: How It Differs from Block Storage

    Object storage keeps data in buckets as independent objects containing the data, a unique key and metadata rather than filesystem blocks. Applications typically access these objects through an HTTP-based, S3-compatible API. Block storage presents a disk volume to a server, where the operating system runs a filesystem or database. The object model is evaluated for media, backups, archives and data lakes, while the block model suits operating-system disks, databases and workloads that need low-latency random reads and writes.

    An S3 migration is more than copying files. A controlled move combines source inventory, required API behaviors, metadata and versions, a trial copy, an integrity check, final delta synchronization and a rollback plan. Test the operations your application uses on the target service.
