Amazon's Jeff Barr, in a blog post, writes that the prices apply to purchases made on or after today, March 5, and it provides a guideline for how to buy: those running servers less than 15% of the time should stick to on-demand; those between 15% and 40% should opt for Light Utilization Reserved Instance; between 40% and 80% is Medium; and higher than that is Heavy.

In light of light utilization, genes for a PR and retinal biosynthesis in addition to those for light-sensing proteins exist in the DSW-6 genome.
One of the most critical factors for biomass production is the efficiency of light utilization.
Additionally, the hierarchical hollow spheres benefit for light scatter and multiple reflections among ZnO@TiO2 composite photocatalyst, which would enhance the effectiveness of light utilization [10, 21, 22].
However, the STH efficiency will be saturated once the dosage increased to about 100 mg, suggesting there exists an optimum dosage for the light utilization.
We present a holey titanium dioxide (TiO2) film combined with a periodically aligned ZnO nanorod layer (ZNL) for maximum light utilization in dye-sensitized solar cells (DSCs).
Our observations do not differentiate between these two possibilities, but exclude that the presence of oxygen is obligate for photosynthetic light utilization in D. shibae.
Facing the issues for ineffective visible light utilization, insufficient separation of photogenerated electron-hole pairs of WO3 photoanode, herein, ultrasmall MoS2 quantum dots (QDs) are exploited as surface sensitizers to boost the photoelectrochemical (PEC) properties of MoS2/WO3.
This study could shed light on 0D/2D interface engineering of carbon quantum dots based heterojunctions with enhanced photoactivity for full spectrum light utilization in pollutant degradation and energy conversion.
Constructing semiconductor heterojunction with optimal structure and composition is highly desired to maximize the solar light utilization for photoelectrochemical (PEC) water splitting.
The FDTD simulation results demonstrated the better light utilization efficiency for the proposed novel mixed 2D/1D hierarchical structure and subsequently resulted in larger effective heterostructure interface area of photoanode which means the increased heterostructure interface area while maintaining evenly distributed light absorption especially at the bottom zone of 3D nanostructure.
