# Private cloud and cluster tools Kit: Apache projects for small business October 29, 2026. [Read the article](https://jwatte.com/blog/apache-private-cloud-cluster-tools-small-business/). ## How to use this kit Write down which control or recovery requirement ordinary rented servers cannot meet. Give the requirement to a named IT operator and ask for a topology drawing and a restore plan. The catalog has no owner-run projects in this group. Treat demonstration minima as trial requirements, not proof of production resilience. No installation or benchmark is claimed here. ## IT project cards ### CloudStack Fits a business operating computing environments, such as a machine shop developing equipment software or an ecommerce team needing repeatable isolated environments. [Installation requirements](https://docs.cloudstack.apache.org/en/latest/installguide/overview/index.html): management/database/storage can share a machine with 4 GB RAM and 250 GB local disk, 500 GB recommended; separate virtualization host needs hardware virtualization, 4 GB RAM and 36 GB disk. Two machines make a trial, not a resilient cloud. Start with the [official installation guide](https://docs.cloudstack.apache.org/en/latest/quickinstallationguide/qig.html). Ask who designs private networking, backs up management and guest data, patches the hypervisor and tests loss of the storage host. Compare ordinary rented application VMs before commissioning a cloud. The price floor below deliberately remains incomplete until networking, storage and availability are quoted. ### OpenWhisk Fits developer-built functions, such as a print shop's thumbnail preparation or a delivery firm's draft summaries. The [Kubernetes deployment guide](https://github.com/apache/openwhisk-deploy-kube/blob/master/README.md) gives a 2 vCPU/4 GB worker floor for its testing configuration; local Docker trials are also documented. It is not a production minimum. IT must operate the control plane, workers, persistence and ingress for a production system. The separate standalone runner uses development defaults and can lose in-memory changes. Ask how retries avoid duplicate actions, which data is persistent, and who tests recovery. Start with harmless copied inputs and a read-only output review. Lambda's unit-priced event functions are the comparator below. ### Karaf Fits a developer's Java integration runtime, such as a wholesaler's shipping connector or a property manager's maintenance API. [Get started](https://karaf.apache.org/get-started) with the official distribution and a compatible Java installation; the [manual](https://karaf.apache.org/manual/latest/) states Java 8+ and 50 MB for the binary, not an application memory minimum. Our 2 vCPU/4 GiB allocation is a test assumption. Ask who patches bundles, protects the management shell and restores application state. Compare App Platform only for a stateless HTTP container with external state; its ephemeral filesystem does not replace persistent local storage. Back up configuration and deployment artifacts, rotate credentials and test updates before changing the running service. **Airavata.** A small materials-testing firm with ten technical staff might need a portal into scientific computing resources. The [installation guide](https://docs.airavata.org/en/latest/installation/airavata-installation/) describes an Ansible standalone inventory covering a database, identity service, message broker, coordination, application and portal. One inventory is not one simple application. No universal hardware floor is published there, and old operating-system examples need review. Our allowance is 6 to 16 hours/month across the platform, plus custom integration. [SciGaP](https://scigap.org/) offers hosted science-gateway infrastructure; no public price was verified, so request terms. Ask who controls research-resource credentials and how a failed job is reconciled. **Brooklyn.** A six person software integrator supporting retailer clients might use infrastructure blueprints to reproduce environments. The [requirements page](https://brooklyn.apache.org/v/latest/ops/requirements.html) gives a development example of 1 vCPU, 3.75 GiB RAM and 4 GB disk; larger production guidance is 2 or more cores, 8 GB RAM and 100 GB disk. A Medium server fits that runtime allowance; the machines it manages cost extra. Use the [archive-based start guide](https://brooklyn.apache.org/v/latest/start/running.html). Allow 6 to 16 platform hours/month because credentials and deployment changes are powerful. A simpler HTTP application could use the $50 App Platform container below instead; that is not a multi-cloud orchestration replacement. No fixed managed Brooklyn price was verified. **Helix.** A 20 person delivery-software business might need to distribute partitions across its application servers. The [quickstart](https://helix.apache.org/1.4.3-docs/Quickstart.html) starts ZooKeeper and multiple participants to demonstrate failures. It is an older architectural example, not a hardware minimum for the current release. Production needs the application participants, controllers and resilient coordination sized together. Budget 6 to 16 hours/month for the platform, with application engineering separate. No fixed managed Helix price was verified; obtain a quote or ask whether a managed database removes the requirement. Different coordination APIs are not interchangeable without code changes. **VCL.** An eight person training company might reserve remote desktop environments for classes. The [2.5.2 installation guide](https://vcl.apache.org/docs/VCL252InstallGuide.html) can put its database, web portal and management node together or apart; guest hosts and images are additional. It gives no universal RAM minimum. Use a supported OS and reserve 6 to 16 administration hours/month for images, access and recovery. Before storing student education records, check applicable FERPA requirements. [Amazon WorkSpaces pricing](https://aws.amazon.com/workspaces/desktop-as-a-service/pricing/) includes an Oregon Windows Standard example at $44/desktop/month with 175 GB root and 100 GB user volumes. Eight desktops would be 8 x $44 = $352/month before extras; this is hosted desktops, not a full VCL equivalent. Ask about image licensing, export and classroom peaks. **YuniKorn.** A 20 person ecommerce business with an existing Kubernetes cluster might need to keep overnight data jobs from competing with order services. The [deployment modes guide](https://yunikorn.apache.org/docs/user_guide/deployment_modes/) puts this scheduler inside Kubernetes; it is not an independent server to buy. No universal RAM minimum is stated. Our shared cluster oversight allowance is 6 to 16 hours/month, not an extra charge per scheduler component. [DigitalOcean Kubernetes](https://www.digitalocean.com/pricing/kubernetes) lists a free standard control plane or $40/month for high availability, with workers and storage extra. Its default scheduler may already suffice; that offering is not managed YuniKorn. Ask how scheduling changes are tested and rolled back. **ZooKeeper.** A 15 person manufacturer may inherit a vendor application requiring shared configuration and leader coordination. The [administrator guide](https://zookeeper.apache.org/doc/current/zookeeperAdmin.html) recommends at least three servers on separate machines for a fault-tolerant ensemble. Three Small servers are 3 x $24 = $72/month before backups and 6 to 16 monthly administration hours. The 4 GiB allocation is our assumption; load-test memory and disk behavior and avoid swapping. A quorum is not a backup, and putting all replicas on one host defeats the purpose. No standalone managed ZooKeeper price was verified. Ask the vendor for a supported managed option and a maintenance quote; do not substitute a different coordination service without its approval. ## Developer reminders - **Aries:** your Java supplier may use these modular enterprise components; ask for the actual component versions, not just the umbrella name. - **Curator:** this client library helps application code use ZooKeeper; installing it does not supply the three-server ensemble. - **Felix:** modular Java applications may use the framework and its related components, which have separate release schedules. - **Libcloud:** your developer can call different cloud APIs through Python; the credentials it uses still need limited permissions and rotation. - **OpenServerless (Incubating):** its [CLI instructions](https://openserverless.incubator.apache.org/docs/installation/install-cli/) say convenience builds are not official Apache releases or production ready. Treat it as development work, with no verified numbered release in this catalog. ## Full group table Registry data can lag. Artifact dates are file modification dates. Aries represents Proxy and Felix represents Framework; other components have their own releases. Incubating projects are not yet fully endorsed by the ASF; see the [incubation policy](https://incubator.apache.org/policy/incubation.html). | Project | What it does | Who runs it | Latest recorded release and date | |---|---|---|---| | [Apache Airavata](https://airavata.apache.org) | Coordinates scientific applications and their computing resources. | Your IT department or provider | [0.17; 2019-03-21](https://downloads.apache.org/airavata/0.17/) (file date) | | [Apache Aries](https://aries.apache.org/) | Supplies enterprise components for modular Java applications. | Your developer | [2.0.0; 2026-10-19](https://downloads.apache.org/aries/) (file date) | | [Apache Brooklyn](https://brooklyn.apache.org) | Deploys and manages applications from repeatable infrastructure descriptions. | Your IT department or provider | [1.1.0; 2024-02-19](https://downloads.apache.org/brooklyn/apache-brooklyn-1.1.0/) (file date) | | [Apache CloudStack](https://cloudstack.apache.org) | Builds and manages a private cloud of virtual machines and networks. | Your IT department or provider | [4.23.0.0; 2026-09-02](https://github.com/apache/cloudstack/releases/tag/4.23.0.0) | | [Apache Curator](https://curator.apache.org/) | Makes it easier for Java developers to use ZooKeeper safely. | Your developer | [5.9.0; 2025-06-26](https://github.com/apache/curator/releases/tag/apache-curator-5.9.0) | | [Apache Felix](https://felix.apache.org) | Provides the runtime and tools for modular Java applications. | Your developer | [7.0.5; 2022-06-03](https://downloads.apache.org/felix/) (file date) | | [Apache Helix](https://helix.apache.org) | Coordinates how distributed applications share work and recover from server failures. | Your IT department or provider | [2.0.1; 2026-09-03](https://github.com/apache/helix/releases/tag/helix-2.0.1) | | [Apache Karaf](https://karaf.apache.org) | Hosts modular Java applications and their supporting services. | Your IT department or provider | [4.4.12; 2026-09-27](https://karaf.apache.org/download.html) | | [Apache Libcloud](https://libcloud.apache.org) | Lets Python applications manage services from different cloud providers. | Your developer | [v3.9.1; 2026-04-16](https://projects.apache.org/json/foundation/projects.json) (registry) | | [Apache OpenServerless (Incubating)](https://openserverless.incubator.apache.org/) | Packages a serverless application platform with supporting data services. | Your developer | Not listed | | [Apache Openwhisk](https://openwhisk.apache.org) | Runs application functions when events or requests arrive. | Your IT department or provider | [2.0.0; 2024-04-07](https://downloads.apache.org/openwhisk/) (file date) | | [Apache VCL](https://vcl.apache.org) | Allocates remote computing environments to users when they need them. | Your IT department or provider | [2.5.2; 2025-03-24](https://vcl.apache.org/downloads/download.cgi) | | [Apache YuniKorn](https://yunikorn.apache.org) | Schedules computing resources across container based workloads. | Your IT department or provider | [1.10.0; 2026-10-06](https://projects.apache.org/json/foundation/projects.json) (registry) | | [Apache ZooKeeper](https://zookeeper.apache.org/) | Coordinates configuration and shared state across distributed applications. | Your IT department or provider | [3.9.6; 2026-09-03](https://downloads.apache.org/zookeeper/zookeeper-3.9.6/) (file date) | ## Cost worksheet Business requirement ___.

Our shared labor proxy is $68.09/hour, from the [BLS sysadmin wage](https://data.bls.gov/oesprofile/?areas=INDUSTRY,STATE,MSA&major_group=150000&measure=01&occupation=151244&year=2025) of $47.66 divided by the [70.0% wage share](https://data.bls.gov/timeseries/CMU2020000000000P). An outside IT provider bills more; get a written quote. [DigitalOcean](https://www.digitalocean.com/pricing/droplets) Small is $24/month for 2 vCPU, 4 GiB RAM and 80 GiB disk; Medium is $48 for 4 vCPU, 8 GiB and 160 GiB. We hold retained backups at 100 GB at both ends. [B2](https://www.backblaze.com/cloud-storage/pricing) costs (100 minus 10) x $0.00695 = $0.6255/month before rounding. We assume no excess egress or chargeable Class D requests. Setup = setup hours x $68.09. Monthly = server charges + backup + monthly administration hours x $68.09. A 36 month total is setup + 36 x monthly. Savings = alternative total minus self hosted total; break even is ceiling(setup difference divided by monthly savings), or never if ongoing self hosting costs more. Our IT platform range is 24 to 60 setup hours and 6 to 16 administration hours/month. A packaged single-runtime service uses 4 to 12 and 1 to 3. These are assumptions, not project staffing promises. Application development, migration, training, tax, major incidents and common application maintenance are excluded. Alternative incremental setup is assumed zero for existing managed-service accounts and prepared applications, not zero real adoption effort. The unmanaged two-VM comparison instead includes its own setup, backups and operating labor. ### CloudStack capacity floor versus two rented application VMs Two node size references: [Linode 32 GB/640 GB disk](https://api.linode.com/v4/linode/types) at $192/month and [Vultr CPU bare metal](https://www.vultr.com/pricing/) starting at $120/month, totaling $312. This is not a validated cross-provider deployment. Private connectivity, storage placement, availability and stock need a quote; do not run shared storage across a public network from this arithmetic. Alternative: two DigitalOcean Medium VMs, 2 x $48 = $96/month, a narrower outcome with different capacity and control. Both cases use fixed node counts; CloudStack labor is 24 to 60 setup hours and 6 to 16 monthly hours. The two rented VMs include 8 to 24 setup hours and 2 to 6 monthly hours for OS operation, plus the same backup allowance; monthly = $96 + $0.6255 + (2 to 6) x $68.09. 100 GB retained backups is a planning input, not a guest-dataset guarantee. | Cost | Low labor case | High labor case | |---|---:|---:| | Setup | $1,634 | $4,085 | | Monthly operations | $721 | $1,402 | | Self hosted 36 month floor | $27,596 | $54,560 | | Alternative monthly | $233 | $505 | | Alternative, 36 months | $8,926 | $19,820 | | Savings from self hosting | Negative $18,670 | Negative $34,740 | | Break even month | Never | Never | ### Setup time when Claude or ChatGPT does the typing We keep the machine shop's $312 CloudStack server floor and 100 GB backups; topology still needs a quote. Hours are our assumptions, including prompting, review, testing and corrections. Studies do not measure Apache setup savings; [METR found slower work in its 2025 experiment](https://metr.org/blog/2025-07-10-early-2025-ai-experienced-os-dev-study/). | CloudStack floor, paired assumptions | Low case | High case | |---|---:|---:| | Manual setup hours | 24 | 60 | | AI setup hours (65% / 90% of manual) | 15.6 | 54 | | Manual monthly admin hours | 6 | 16 | | AI monthly admin hours (80% / 100% of manual) | 4.8 | 16 | | Human review within AI setup hours | 6 | 18 | | Human review within AI monthly hours | 3 | 8 | | Manual 36 month total | $27,596 | $54,560 | | Claude Max 5x subscription, 36 months | $25,983 | $56,051 | | ChatGPT Pro 100 subscription, 36 months | $25,983 | $56,051 | | Claude Opus 5.5 API, 36 months | $24,155 | $54,613 | | GPT-6 Astra API, 36 months | $24,270 | $55,306 | | Opus API setup / monthly token cost | $3.82 / $1.91 | $30 / $12 | | Astra API setup / monthly token cost | $9.85 / $4.925 | $75 / $30 | | Unchanged two-VM alternative, 36 months | $8,926 | $19,820 | We charge one separate setup month at $100, then allocate $50/month for 36 operating months to [Claude Max 5x](https://support.claude.com/en/articles/11049741-what-is-the-max-plan) or [ChatGPT Pro 100](https://chatgpt.com/pricing/). Other work must use the remaining half; total allocations cannot exceed the subscription. Dedicated use adds $1,800. Allowances differ; check limits and charge extra usage. API assumptions total 1 to 5 million setup input tokens and 100,000 to 500,000 output; monthly input is 500,000 to 2 million and output 50,000 to 200,000, including retries. Low input is 30% ordinary, 10% short cache writes and 60% reads; high input is uncached. Per million input/write/read/output rates are $4/$5/$0.20/$20 for [Opus](https://platform.claude.com/docs/en/about-claude/pricing) and $10/$12.50/$1/$50 for [Astra](https://developers.openai.com/api/docs/pricing), using standard short-context pricing. Each call must fit that band. T0/Tm are setup/monthly tool fees; round totals after calculation. ```text L = $68.09/hour; H = $312 + $0.6255/month S = manual setup hours; A = manual monthly admin hours q = 0.65 low or 0.90 high; r = 0.80 low or 1.00 high Manual setup = S x L; Manual monthly = H + A x L AI setup = S x q x L + T0; AI monthly = H + A x r x L + Tm 36 month total = setup + 36 x monthly; saving = manual total minus AI total API fee = (ordinary input x input rate + cache writes x write rate + cache reads x read rate + output x output rate) / 1,000,000 ``` The conclusion stays: two rented application VMs remain cheaper, with no break even against that alternative. High-case subscriptions save no monthly labor and exceed manual CloudStack cost from month 7. Low-case subscriptions save $1,613 against manual operation. Claude Code or [Codex](https://developers.openai.com/codex/cli) can draft CloudStack configuration and recovery commands. [Desktop Commander](https://raw.githubusercontent.com/wonderwhy-er/DesktopCommanderMCP/main/README.md), on the new server or through authorized SSH, can install packages, edit configuration and read management logs. Its free local service is assumed; optional [$20/month Remote Pro](https://desktopcommander.app/pricing/) adds $380 with the same allocation. [Claude in Chrome](https://support.claude.com/en/articles/12012173-get-started-with-claude-in-chrome) can inspect provider, Cloudflare and CloudStack dashboards while we watch. [ChatGPT's cloud browser](https://help.openai.com/en/articles/20001280-using-cloud-browser-in-chatgpt) uses a separate browser where available. Use new test machines, approve commands or restrict the sandbox, and keep secrets out of chat. Watch dashboard actions and review every change, including network isolation and a restore test. Use subscriptions for a person directing supported tools and API keys for custom automation. We still own backups, updates and topology approval. See the [private cloud post](https://jwatte.com/blog/apache-private-cloud-cluster-tools-small-business/) for the original comparison and topology limits. ### OpenWhisk noncritical pilot versus Lambda Event Functions [Lambda](https://aws.amazon.com/lambda/pricing/): US East (N. Virginia) x86 $0.20/million requests and $0.0000166667/GB-second, with one million requests and 400,000 GB-seconds monthly allowance. Our 100,000 to one million invocations each use 1 GB for one second: $0 to $10/month base runtime charges if the account's free allowance is unused. Extra logs, storage, networking and triggers excluded. One Small self hosted evaluation machine, 24 to 60 setup and 6 to 16 monthly hours, 100 GB backups; production requires a separate topology quote. | Cost | Low labor case | High labor case | |---|---:|---:| | Setup | $1,634 | $4,085 | | Monthly operations | $433 | $1,114 | | Self hosted, 36 months | $17,228 | $44,192 | | Alternative monthly | $0 | $10 | | Alternative, 36 months | $0 | $360 | | Savings from self hosting | Negative $17,228 | Negative $43,832 | | Break even month | Never | Never | ### Karaf runtime versus hosted stateless container [App Platform](https://www.digitalocean.com/pricing/app-platform): shared 2 vCPU/4 GiB container $50/month; review [storage and protocol limits](https://docs.digitalocean.com/products/app-platform/details/limits/). One Small self hosted server, 4 to 12 setup and 1 to 3 monthly hours, 100 GB retained backups. External application state and code work are common excluded costs; high availability is outside this single-instance comparison. | Cost | Low labor case | High labor case | |---|---:|---:| | Setup | $272 | $817 | | Monthly operations | $93 | $229 | | Self hosted, 36 months | $3,610 | $9,057 | | Alternative monthly | $50 | $50 | | Alternative, 36 months | $1,800 | $1,800 | | Savings from self hosting | Negative $1,810 | Negative $7,257 | | Break even month | Never | Never | ## Sources Read October 29, 2026.
