Upatikanaji wa Seva na SLA kwa wanaoanza
Ukitumia mashine ya kuajiri, wakati wa kazi ni muhimu sana.
Wakati wa kupumzika ni wa hali ya juu sana hivi kwamba, kwa kawaida, mfanyakazi huchunguzwa anapoona saa hizo mara chache tu baada ya saa za kazi.
Ni Nini Kinachotumika Wakati wa Urefu?
Server uptime is a metric that shows how long that server is operating normally during a given period. This value is usually expressed as a percentage and serves as an important standard for measuring server reliability.
Wakati wa kupumzika ni wa hali ya juu sana hivi kwamba, kwa kawaida, mfanyakazi huchunguzwa anapoona saa hizo mara chache tu baada ya saa za kazi.
Jinsi Wakati Unavyohesabiwa na Kufanywa Kusonga Mbele
Muda wa ziada unakadiriwa kwa kutumia kanuni ifuatayo.
Uptime (%) = (Annual Operating Time / Total Annual Time) × 100
Wakati wote wa kila mwaka ni siku 365.25 ▶ saa 24 = saa 8766 wakati miaka inaposonga.
Wakati wa kushuka kwa kila asilimia ya wakati ni kama ifuatavyo.
| Uptime | Annual downtime |
|---|---|
| 99% | About 87.7 hours (about 3.65 days) |
| 99.9% | About 8.77 hours (about 52.6 minutes) |
| 99.95% | About 4.38 hours (about 26.3 minutes) |
| 99.99% | About 52.6 minutes |
| 99.999% | About 5.3 minutes |
Uhusiano Muhimu Kati ya Wakati wa Urefu na Wakati wa Kufiwa
A Service Level Agreement (SLA) is an agreement between a service provider and a customer that defines agreed service-quality conditions.
Ugonjwa wa SLA unatia ndani kuhakikisha kwamba mtu atafika kwa wakati, na pia wakati mwingine atashindwa kufanya hivyo, mbinu za kupata habari, na nyingine nyingi.
Aina Mbalimbali za Ufadhili Katika SLA
Ni muhimu kwamba SLA ieleze waziwazi malipo yanayotolewa wakati wa kupanda chini ya kiwango kilichothibitishwa.
Njia za kawaida za kulipia gharama za huduma hutia ndani malipo ya chini na malipo ya kifedha kwa ajili ya hasara.
Makusudio ya Kawaida ya Wakati wa Cheo cha Juu na Madarasa Makubwa Zaidi
Kituo cha kuhifadhi habari kinaonyeshwa kupitia orodha ya mambo yanayoonyesha jinsi ya kushughulikia mambo, na hivyo vinahusiana na wakati wa ziada.
- Tier 1: Uptime 99.671%, allowable downtime 28.8 hours per year
- Tier 2: Uptime 99.749%, allowable downtime 22 hours per year
- Tier 3: Uptime 99.982%, allowable downtime 1.6 hours per year
- Tier 4: Uptime 99.995%, allowable downtime 26.3 minutes per year
Kwa ujumla, ili mtu atumie kampuni ya kukodi kodi inayotumia kituo cha habari cha Tier 3 au cha juu zaidi kinapendekezwa.
Hatari za Kuwatumikia Wahaini: Athari za Kibiashara na Hasara Zilizokadiriwa
Lower uptime causes website access failures and service interruptions, which can have a serious impact on business. In the case of an e-commerce site, for example, one hour of downtime can potentially cause millions of yen in lost sales.
(Example) For an e-commerce site with annual sales of 100 million yen, what is the estimated annual loss caused by 99% uptime?
100 million yen ÷ 365 days × 3.65 days ≒ about 1 million yen
Kutazama jambo hilo kwa njia hiyo hufanya iwe rahisi zaidi kuelewa jinsi wakati ulivyo muhimu kwelikweli.
