What’s on the Load Balancing poster
A 5-row table: Algorithm · Sends to · Best when.
The common algorithms and where each fits.
- Round robin — Each server in turn — Requests cost the same
- Least connections — Fewest active connections — Requests vary in duration
- Weighted — Proportional to capacity — Servers differ in size
- IP hash — Same client → same server — Sticky sessions needed
- Least response time — Fastest responder — Mixed server health
Health checks matter more than the algorithm. A balancer that keeps sending traffic to a dead node is worse than none.

- Who is the Load Balancing poster for?
- Load Balancing belongs to the Computing section rather than to a school year, because computing is not something one grade owns. Anyone learning systems can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Load Balancing poster?
- Round robin assumes every request costs the same. It rarely does. A wall chart earns its place by being glanceable from where the work is happening, so Load Balancing belongs on the wall where that computing work actually happens, within glancing distance, rather than filed away.
- What other posters go with Load Balancing?
- Caching, Concurrency & Parallelism and DNS sit alongside Load Balancing in the Computing section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.CachingConcurrency & ParallelismDNS
- Is the Load Balancing poster free to download and print?
- Yes. Load Balancing downloads as a free PDF with no account, no email and no watermark, like everything else in the Computing section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Load Balancing poster print at?
- Load Balancing is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Load Balancing loses nothing.Printing guide
