Where are your servers? Are you self-hosting? Have you thought about professional hosting? What services does a professional hosting service offer? Do you need shared hosting? Do you need a VPS? What's a VPS? What's a colocation site? How much will all this cost?
Come share your experiences with self-hosting, shared hosting, and VPSes. Bob and Marc have the questions, and special guest Mark Steffen from indieServe Networks will have the answers.

Meeting Notes
- Today's guest is Mark Steffen from indieServe Networks
Selecting a hosting provider
- There's no "One size fits all"
- What do you need?
- Disaster recovery?
- Microsoft licensing?
- E-mail hosting?
What kinds of servers for a host?
- Dell servers at one place
- Had HPs, didn't mind them
- indieServe has some HP servers for colocation
- Lenovo, but there was BIOS based malware
- Liked IBM servers, anecdotally liked the reliability
- indieServe has all Lenovo servers
Offsite Hosting Problems?
- Shared hosting was OK for a while, but host was asking for more money
- Another company seemed perfect shared hosting (using WordPress),
- Works today, but lots of complaints on Facebook, so he no longer trusts
- Backups?
- Yes, keeping your own backups in addition to using the hosts' backups
indieServe Networks
- indieServe is hosting for KWLUG, KWVoIP, FairvoteWRC, KWPeace, &c.
- About $10/month for shared host
- No limits but on the honour system
- Keep it to one company per shared host
- Local non-profits may be able to get really good deal -- talk to Mark Steffen
- Also has VPS (Virtual Private Servers)
- Can do hosted Windows servers or domain
- Good for small file sharing systems
- Microsoft has a specific licensing arrangement for hosting providers
- Cost based on cores and sockets, plus number of customers
- Not cheap, $100's /month
- Similar model to Azure or Amazon AWS
Offsite Backups
- Some customers use offsite hosting only for data replication (disaster recovery)
- Do keep offsite backups encrypted
- For any backup solution check with Legal for PIPEDA legislation
- Cheap backup? 20¢/GiByte for storage is typical
- Backup software:
- Duplicity for Linux
- Cloud Berry for backup service
- DupliCaddy for Windows (Open Source, Beta software,supports SQL, kinda slow)
- For Windows, do full backup, then everything is incremental afterwards
- But it keeps a synthetic "Full" in the background
- With S3 or Azure, you can restore to EC2 -- get (almost) instant restore on external VPS -- really cheap disaster recovery
- Back Blaze (personal backup for $5/month, also B2 backup storage, .02¢/Gibyte?, $10/month for 1 TByte?)
- indieServe keeps hard backups (USB drives stored offsite)
Backup horror stories
- Hijacked truck (backups not encrypted, nobody knows who now has access to backup data)
- Encrypted backups corrupted (physical disk damage corrupted one block of data, cypher block chaining made rest of backup inaccesible)
- Bulk files corrupted (backup file is OK, but contained invalid data, making rest of the backup invalid)
- Tape backup is still the most dense storage for immutable backups
- Mark Steffen has techniques for redundant backup storage (good for ransomware attacks, &c.)
- How much backup do you need?
- How much data can you afford to lose?
- Have at least one automated backup in place
Selfhosting?
- Run your own service on a VPS or shared host (XMPP, Wiki, Social media) instead of using Facebook, Google, Twitter)
- Manage your own server, colocated in a datacentre
- Getting a DSL line (with multi-link support), and running a server on premises
- Managed hosting - servers in house or colo, but contract out the SysAdmin
Webhosting Management
cPanel
- Set up WordPress, &c.
- Handles updates, patch management, backups, email
- Installatron for managing applications
- Varnish is a cache in front of Apache, for bursty traffic
- cPanel is pricey? $20/month for bare metal, less for a VPS
- Keeping cPanel on a VPS makes it portable, allows cPanel admin to perform maintenance with no downtime
Zenserver
- A Virtual Machine host
- The free version is pretty unrestricted
- Use Zenserver to run cPanel
Cloud Linux
- uses CageFS,
- isolates users from each other
Other panels?
- CentOS Web Panel
- ISP Config
- Ubuntu MAAS
- WebMin, VirtualMin
- WHM is the management tool for cPanel
- WHMCS is a shopping cart / billing system for hosting
- But these apps may have security issues (PHP doncha know)
Reseller hosting
- Perhaps for Web developers, who want to manage resources for their customers
- Can add multiple accounts, lets hosting provider manage growth and resources
- Could be unlimited accounts, but typically 300 GBytes, good for about 50 accounts
